I got it on Amazon! So I ordered 3 rolls, and I definitely could’ve used 4 (the wall behind the crib, is piecemeal/blank)… if I remember correctly I measured the wall at about 15 feet wide by 8 feet tall. I went with their suggested amount but since it’s a pattern that you have to line up, I should’ve gotten the extra roll.
