Custom drapes can do a lot of different jobs on an event site - stage masking, AV backdrops, ceiling treatments, booth dividers, wedding walls, hospitality installs. The problem is that each of those jobs has different requirements. A velour stage masking panel and a sheer voile ceiling treatment are both "custom drapes" in the same way that a pickup truck and a sports car are both "vehicles." Treating them the same way gets you into trouble.
This guide covers what actually drives the decision: fabric, fullness, hardware, light control, FR compliance, and construction. Not in theory - in the context of real event work where the drape needs to perform on site, not just look good in a swatch photo.
At Liba Fabrics, we've been supplying event and theatrical draping fabrics and custom-sewn panels for years. This is how we think about it.
What Should the Drapes Do?
Before you pick a fabric or spec a fullness level, answer this one question: what does the drape need to do in the room?
It sounds obvious. It gets skipped constantly.
A stage masking panel needs to kill light, hang dead straight, and survive a hundred load-ins. A wedding ceiling treatment needs to move softly, photograph well, and make the room feel like something. A trade show booth divider needs to be easy to install, reusable, and sized for a 10x10 or 10x20 without drama. These are three completely different briefs.
Here's a fast way to sort it:
Production and masking - stages, AV backdrops, reveal curtains, camera walls. Priority is light control, clean hang, and FR compliance. Fabric weight matters. Fullness is secondary to coverage.
Decorative draping - weddings, galas, ceiling treatments, venue walls, hospitality installs. Priority is movement, color, and how it photographs. Fabric weight is less important. Fullness is everything.
Space division and booth work - trade shows, corporate events, temporary layouts. Priority is ease of install, reusability, and clean finish. Neither the heaviest nor the lightest option. Somewhere practical in the middle.
Most orders fall cleanly into one of these. Some span two. If you're sourcing finished panels rather than fabric by the yard, our custom sewing team works through exactly this process before anything goes into production - starting with the job, not the fabric.
| Fabric Type | Best For | Strengths | Limitations |
|---|---|---|---|
| IFR Velour / Velvet | Stages, AV masking, blackout looks | Light absorption, rich texture, strong coverage | Heavier, higher cost |
| Sheer Voile | Weddings, ceiling draping, layered installs | Soft diffusion, light movement | Limited opacity |
| Satin | Decorative panels, formal event drapes | Smooth finish, subtle sheen | Can reflect lighting |
| Poplin | Clean event panels, trade show drapes | Smooth, practical, versatile | Less dramatic texture |
| Spandex | Truss covers, shaped displays | Stretch fit, clean modern look | Not ideal for traditional fullness |
Choosing the Right Fabric for Custom Drapes
Fabric choice determines how a drape looks, hangs, blocks light, stores, and holds up after the tenth install. There's no universal right answer. There's only the right answer for the specific job.
Here's how the main categories break down for event work.
IFR Velour and IFR Fire Velvet - Production, Masking, and Stage Work
If the priority is light control and clean visual coverage, velour and velvet are where you start. The pile surface absorbs light instead of reflecting it, which matters when you have stage lighting, screens, or cameras in the room. A flat fabric in the same situation will catch and throw light in ways that read badly on camera and distract from the stage.
Liba carries IFR Velour in 10oz, 15oz, and 23oz weights, plus 25oz IFR Charm Velour for the heaviest light control applications, and IFR Fire Velvet for installs where you want a softer, more decorative surface without giving up FR compliance.
The weight progression matters. 10oz works for lighter masking applications and pipe and drape setups. 15oz and 23oz are better for stage legs, borders, and travelers where the drape needs to hang with authority and move predictably. 25oz Charm is the choice when nothing else will do - full blackout performance, maximum pile depth, significant weight to manage on install.
The trade-off is real: heavier panels need stronger support, more careful handling, and longer install times. That's not a reason to avoid them. It's a reason to plan for them.
Sheer Voile, Chiffon, and Decorative Fabrics - Weddings, Ceilings, and Venue Work
Sheers are the opposite problem. The fabric is light, which is the point - but light fabric used incorrectly looks cheap, thin, and flat under event lighting.
The two most common mistakes with sheer draping: not enough fullness, and not enough layers. A single panel of voile at 1.5x fullness on a bright venue wall will look like a curtain from a college dorm. The same voile at 2.5x fullness, layered, with the right lighting behind it, looks like a completely different product.
Our 118in Voile and 118in Batiste are the workhorses for ceiling treatments and soft wall draping. Wide width means fewer seams on large installs. The IFR compliance means you're not scrambling for certs at a hotel or convention venue that requires them.
For events where the look needs to be richer - satin sheen, structured hang, formal finish - IFR Shantung and Mystique Satin give you more surface presence than a sheer without going to full velour weight.
The rule with decorative draping: buy more fabric than you think you need. Fullness is not the place to cut costs. A drape that looks thin on install day cannot be fixed on site.
How to Measure and Specify Custom Drapes
This is where most ordering mistakes happen - not in fabric selection, but in how the order gets written up.
A quote for custom drapes needs six things at minimum: finished width, finished height, fabric, fullness ratio, top finish, and bottom finish. Missing any one of those creates either a back-and-forth that delays production or a panel that technically fits but performs poorly in the room.
Width and Height
Start with the actual area to cover, then work backwards. Account for ceiling clearance, floor contact, and hardware. A panel sized to the pipe length without accounting for the crossbar hardware can end up two inches short on each side - which reads as a mistake even if the fabric is perfect.
For stage and production work, panels typically hang slightly above the floor - clean, no break, nothing to catch on during load-in. For weddings and decorative installs, a slight floor break is often intentional. It reads as softer and more luxurious. Decide before production, not on install day.
Fullness
Fullness is the multiplier between the finished width of the panel and the width of fabric used to make it. A 10-foot wide panel at 2x fullness uses 20 feet of fabric. At 2.5x, it uses 25 feet. That difference shows up in the cost and dramatically in the look.
Standard guidance:
- Sheers and lightweight fabrics: 2x to 2.5x minimum. Less than that and they look flat.
- Mid-weight decorative fabrics: 1.5x to 2x. Enough for soft folds without excessive bulk.
- Heavy velours and velvets for masking: 1.5x is often sufficient. The weight of the fabric creates the visual presence; you don't need the same fullness as a sheer.
The most common mistake is applying the same fullness spec across every fabric type in an order. It doesn't work that way.
Top and Bottom Finishes
Top finish should match how the panel installs. Pockets for pipe and drape crossbars. Webbing, Grommets and Ties for Track and Rigging Points.
Bottom finish matters more than people think. A clean hem keeps the panel hanging straight and makes it easier to store and transport without permanent creasing. Weighted hems are worth considering for outdoor installs or any situation where air movement is a factor.
If you're ordering finished panels through our custom sewing department, we'll confirm all of these specs before anything goes into production. The goal is that the panel arrives ready to install - not ready to be figured out on site.
FR Compliance, Durability, and Getting the Order Right
Fire retardancy is not an optional upgrade for most commercial event work. It's a baseline requirement that venues, hotels, convention centers, theaters, and public event spaces enforce - often strictly, and sometimes at the last minute.
The time to confirm FR requirements is before the order goes into production. Not when the venue asks for certificates on load-in day.
IFR vs. Topical FR
There are two types of flame resistance in event fabric. Inherently flame retardant - IFR - means the FR property is built into the fiber itself during manufacturing. It doesn't wash out, wear off, or degrade with normal use. Topically treated FR means a chemical treatment has been applied to the surface of the fabric after manufacturing. It can be effective but it's not permanent - washing, heavy use, and time all reduce its effectiveness.
For commercial event draping that gets handled, transported, stored, and reused repeatedly, IFR is the better long-term choice. The cert holds up. The compliance doesn't depend on how the panels were laundered six months ago.
At Liba Fabrics, our IFR and FR fabrics are certified for NFPA 701, California Title 19, and CAN/ULC-S109-14 depending on the type of drapes you purhcase. Certificates are available on request. If you're ordering finished panels through our custom sewing department, we can confirm the compliance spec before production and include documentation with the order.
Durability Is a Construction Question
A drape used once for a wedding has different durability requirements than a drape in a rental inventory that gets installed and struck fifty times a year. Both are valid use cases. They require different construction decisions.
For high-use rental inventory and production work, the things that fail first are usually the top finish and the hem. Grommets pull out of thin fabric without proper reinforcement. Hems come undone when the panel is folded and stuffed into a bag repeatedly. Stitching at stress points - corners, grommet placements, pocket openings - is where the panel either holds up or doesn't.
When ordering finished panels for high-use applications, specify this upfront. Reinforced webbing at the top, bartacked stress points, and a clean double-stitched hem add minimal cost at the production stage and significant life to the panel in real use.
For single-use or low-use decorative applications - a one-time wedding install, a short-run hospitality project - the construction requirements are lighter. You're optimizing for look and finish, not wear cycles.
Before You Place the Order
To get an accurate quote and avoid back-and-forth that delays production, have these details ready:
- Finished width and height per panel
- Number of panels
- Fabric type and color
- Top, bottom and side finish
- FR compliance requirement and which standard
- Deadline and shipping requirements
The more complete the spec, the faster the quote, the fewer surprises in production, and the better the panel performs when it gets to the event site.
Our custom sewing team works with event professionals, production companies, rental companies, venues, and hospitality purchasers. If you know what you need, we'll produce it to spec. If you're still working through the details, we can help you get there. Either way, the goal is the same - panels that work in the real space, not just in the order confirmation.
Frequently Asked Questions
What's the difference between custom drapes and standard drapes?
Standard drapes are made to fixed sizes and sold off the shelf. Custom drapes are built to your exact specs - finished width, finished height, fabric, fullness, top finish, bottom finish, and FR compliance. Liba Fabrics only produces custom drapes built to your exact specs.
Do I need FR certified drapes for my event?
Most commercial venues, hotels, convention centers, theaters, and public event spaces require it. The specific standard varies - NFPA 701 is the most common in the US, California Title 19 applies in California, and CAN/ULC-S109-14 covers Canadian venues. When in doubt, ask the venue before you order. Finding out on load-in day that your panels don't comply is an expensive problem to solve on site.
What fullness ratio should I use?
It depends on the fabric. Sheers and lightweight fabrics need at least 2x to 2.5x - less than that and they look flat and thin under event lighting. Mid-weight decorative fabrics work well at 1.75x to 2x. Heavy velours and velvets for masking can work at 1.5x because the weight of the fabric does the visual work. Applying the same fullness ratio across every fabric type in an order is one of the most common mistakes we see.
How long does it take to produce custom drapes?
It depends on fabric availability, order volume, and complexity of construction. The best way to protect your timeline is to have a complete spec ready when you place the order - fabric, dimensions, finish, and FR requirement. Incomplete orders take longer because every back-and-forth round adds days. If you have a hard deadline, tell us upfront. We'll tell you honestly whether it's achievable.
What top finish should I specify?
Match the finish to the hardware. Pockets for pipe and drape systems. WGT for tracks and rigging points. If the same panels will be used across multiple venues with different hardware setups, build for the most flexible option - not the most elegant one for a single install.
Can the same drapes be used for multiple events?
Yes, with the right construction. High-use rental inventory needs reinforced top finishes, bartacked stress points, and durable hemming. Panels built for a single decorative install won't hold up the same way. If you're ordering for a rental fleet or production inventory that gets installed and struck repeatedly, specify that upfront so the construction matches the use case.
What's the difference between IFR and topically treated FR fabric?
IFR - inherently flame retardant - means the FR property is built into the fiber. It doesn't wash out or degrade with use. Topically treated FR is a chemical finish applied after manufacturing. It works but it's not permanent - washing and heavy use reduce its effectiveness over time. For commercial event draping that gets handled and reused repeatedly, IFR is the more reliable long-term choice. You can browse all of Liba’s IFR and FR fabrics here.
