I was a little worried about assembling the Pom-poms, but it was really as easy as following the included instructions. Basically you need to fold along preset lines, wrap the included wire around the middle, and then peel each layer out. The bigger ones can take a while (maybe about 10 min each), and I think it's harder to make then looking more even/round compared to the smaller ones.Bought this for a baby shower decoration. Used thin white strings to hang them off a chandelier at different lengths. Looked pretty nice if I say so myself. Obviously hard to store them once assembled, so probably will end up just tossing them. Colors look exactly like in the pictures. overall, glad I bought them.
