It feels like I've made a zillion of these. I placed them in a local art shop and they sold well. I use a heavy weight ruler with the curved side to the inside. I clip the corners of the ruler and cover with duct tape. I call them "Snap Happy" purses. I have also folded an inch strip of corresponding fabric into fourths and top stitched it. Then I cut it about 7", looped it and sewed it up near the top when sewing the side seam. When turned right side out you have a handle and makes it wrist purse.
