A wall totalling 10 ft wide × 8 ft tall needs about 5 bolts of standard 36-inch grasscloth. Each 12 ft bolt yields just one full 8 ft drop, so grasscloth wastes more than patterned paper — and with no pattern to hide seams and colour that varies bolt to bolt, order generously and always from the same dye lot.
Give the total width you're covering and the ceiling height. Grasscloth hangs in vertical drops like paper.
Grasscloth is woven from natural fibres, so shading shifts subtly across and between bolts. Designers "blend" bolts by hanging them in a random order and reversing every other strip so the eye reads the variation as texture. Order from one dye lot to keep it within range.
Most grasscloth is hung paste-the-wall with a clear adhesive to avoid staining the fibre. Seams are butted, not overlapped, and they will be visible up close — that's normal for the material. Keep paste off the face and roll seams gently.
Divide the total wall width by the bolt width for the number of strips, and the bolt length by the ceiling height for strips per bolt. Bolts = strips ÷ strips-per-bolt, rounded up, plus a 15%+ buffer. Order all bolts in one dye lot.
It's woven from natural fibres, so colour and texture vary by nature. Blending bolts — hanging them in random order and reversing alternate strips — makes the variation read as intentional texture.
Yes, slightly. Seams are butted rather than overlapped and remain visible up close. This is inherent to the material and considered part of its handmade character.
At least 15%, more for tall walls. Because you can't re-order the same dye lot later and seams can't be hidden, generous ordering is essential.
