The Spoonflower Handbook is here!
Side note: The wallpaper version is in a smaller scale than fabric because the number of repeats on a roll required me to pick bigger or smaller. i could not have the 3.44 scale. If you are interested in the wallpaper and want the 4.0 size instead of the 3.0 size when ordering, ask before you buy, and I will reset it.
Wallpaper Coverage Calculator
Based on the dimensions you provide, this calculator will determine the number of custom-length sections of paper you'll need to cover any surface. If the height of your surface varies, input the tallest dimension in order for the pattern to line up correctly.
Enter your dimensions in feet (1 foot is 30.48 cm).
