I have had plenty of items ruined by using my scissors to push out corners. I believe I won this tool at the Pueblo West Quilters. I love it. It's for turning corners and sometimes I use the rounded end to flatten rounded edges. It is amazing. I don't think I've ever pushed too hard and made a hole in the fabric.
Go get one of these. Although, I'm not really sure where to go to get one but I'm sure your local quilt store or craft store would sell them.
The "wallies" I made to put in our Quilt Club's boutique. They are cute and convenient. You can slip your i.d. and credit card and a little change inside and put it in your pocket or just use it as a small wallet in your purse. I hope they sell. Our quilt club alsot gets 15% so I feel like I'm helping them too. It's a win/win situation.
