BUYER GUIDESChoosing a Scrim Fabric: Sharkstooth, Muslin, Poly Stretch & FR
‘Scrim’ gets used loosely to mean almost any stage fabric, but the material you actually order changes everything about how your piece looks, lights, and behaves. Sharkstooth, seamless muslin, poly stretch knit, and FR-treated goods each do different jobs, and picking the wrong one is an expensive way to learn the difference.
Here’s a straightforward guide to the main fabric families we work in and how to match one to your show.
Sharkstooth scrim gauze
The open, tooth-weave fabric behind the front-lit/back-lit reveal. Solid when lit from the front, transparent when lit from behind — the classic theatrical illusion fabric for ghost effects, dream sequences, and dissolving a drop into a live scene. Choose it whenever the effect is the point. Black disappears best; white and grey suit projection and bleed.
Seamless muslin
The plain, matte, seamless cotton canvas behind a huge share of productions. It lights and projects evenly with no seam line, dyes and prints beautifully, and is the traditional ground for painted scenery. Pick muslin for neutral backdrops, painted or printed drops, and affordable, forgiving projection and lighting surfaces.
Poly stretch knit
A four-way stretch knit that pulls drum-tight and wrinkle-free over frames and wraps curves and 3-D shapes. It lights up in saturated color, prints edge to edge, and makes sculptural stretch-shape sets possible. Choose it for flawless flat walls, colorful LED-washed surfaces, and any non-rectangular scenic form.
FR treatment across all of them
Flame retardancy is a property, not a separate fabric — sharkstooth, muslin, and poly stretch are all available inherently FR or FR-treated to NFPA 701. Because nearly every venue requires it, treat FR as a default checkbox on your order rather than an upgrade, and match inherent vs. topical to how long the piece must stay compliant.
| Fabric | Signature quality | Best for |
|---|---|---|
| Sharkstooth scrim | Reveal: solid then see-through | Ghost effects, dissolves, portals |
| Seamless muslin | Matte, seamless, paints/prints well | Backdrops, painted drops, projection |
| Poly stretch knit | Drum-tight, wraps 3-D shapes | Stretch sets, color walls, forms |
| FR-treated goods | NFPA 701 compliant | Any venue that requires certification |
