Upholstery, slipcovers, cornhole bags, totes & backpacks, aprons, tool rolls, banners, backdrops, and utility covers.

How does 12oz compare to 10oz?

12oz is thicker and more durable for heavy-use applications; 10oz is easier to drape and great for décor and mid-weight projects.

Preshrunk vs. natural vs. stone washed—what’s the difference?

Natural (loomstate) may shrink ~8–12% on first wash. Preshrunk is laundered to reduce shrinkage. Stone washed is softened with a vintage look; expect ~3–6% shrinkage.

Can you add FR or water-repellent finishes?

Yes—FR and water-repellent treatments are available upon request (lead time/minimums may apply). Contact us for details.

What widths and colors are available?

Common widths include 60" and 72" (varies by style). Choose natural, preshrunk, popular dyed colors, and stone washed finishes.

Recommended needles, thread, and stitches?

Use 90/14–100/16 needles; polyester or cotton-wrapped poly thread; 8–10 stitches per inch for bags or upholstery.

Care instructions

Pre-wash similar to final use. Machine wash warm/cold; tumble dry low or line dry. Expect softening and natural texture after laundering.
