It's taken me long enough (!) but here is finally the pictorial to create my little sewn-shut treat bags I used at the ice cream party.
You will need:
Clear plastic Treat bags
Strips of scrapbook paper
The pictures are probably self-explanatory, but I thought I would just mention that I used strip of glue to hold the paper and doily in place. It made it so much easier that everything was held in place during the sewing.
