This grasscloth wallpaper is gorgeous, by the way — extraordinarily textured and very crisp.
I highly recommend ordering swatches first. Spoonflower has a variety of fabrics and wallpapers, which means colours can print subtly differently — for example, the cottons tend to be a bit more muted, the velvets are more saturated (and the Celosia velvet brings out yellow tones), while the wallpapers have crisp lines on a range of textures.
You can find them all at my Spoonflower shop — and as well as allowing you to buy lengths, Spoonflower also offers some pre-sewn bed and table linens. (And for other objects, there’s Redbubble.)
