The best way to have a good idea is to have lots of them.
I started counting....
and I have sewn 25 Doll Purses! In the process of developing the pattern and finding what did and didn't work, I had pieces left over and I used them to sew 10 smaller versions (top two photos). I've also made a number of samples for shops (bottom photo--Quilts Etc). I have also sewn 3 for my grand daughters. Out of the 25 I've sewn, I have 6 left that haven't sold yet or are on display at shops.
