I have done these before, as I have a good friend that is a children's photographer and wanted a lavender one. I must have used about 200 blooms. It took about 1.5 - 2 hours to do. I used fabric tac and put the beanie on a small ball so I could really squish the flowers together to not see any fabric. She has not yet used it, but when she does, I will post a pic.
