LOVE that sunflower fabric and that purse. I agree that the pocket should be quilted, if only for stability. Most women tend to overstuff their purse pockets and quilting would help stabilize. It only takes a few extra minutes to do a job correctly the first time, so why not just do it?
As far as ironing that CRAPPY glitter fabric, I would iron from the back. The butterflies are BEAUTIFUL, but the manufacturer really cheapens the fabric by tossing glitter on it. Wish they would get that through their heads. :-D
