Here's an envelope purse that I made to fit my flowers in. It took me a couple times before I got the right size to fit them all in. The first bag that I made was a little too big and I know it would get smashed when I mail it so I decided to make a different one.
Here is the pink purse that I first made. I used the crochet flower in the front. I don't have a template because I trashed it accidently and need to make another one.
