problems with purse
I'm hoping some of you who have made purses can help me. I just finished a purse (sorry I can't post a picture - my camera is not working). It came out really cute, but when I put a wallet and other things in it, the edges gap. I took the border off and put in some really stiff stuff I had and sewed it back but it still sags. What am I doing wrong? Is there something else I should be using? Any help would be appreciated!
