So many pretty bow-tucks shown. I have made over 10 and use 4 of them for myself. I use the snap to close mine. I use plastic canvas for the bottom, fitting it between the bottom and lining. I put a few stitches into the canvas at the purse seam to secure it. Wash it in the washing machine and spray starch it while wet and let air dry. I have had no problem. I notice several others also divide the front pocket with stitching in the center. I found that my cellphone fits and stays better doing it that way. Sometimes I shorten the size of the front pocket, making it a bit more user frienly.
Patti, your bags are outstanding. Love them.
