Everyone had good ideas. When I started my 3 DGDs (not all at the same time) I had them make pillowcases. It didn't take very long and they had a finished project to use right away. Three hours isn't a very long time to teach them how to make a quilt, I think you have to skip some of the learning for next time (threading the machine, cutting pieces, etc.) Out of 3 DGDs only one is still interested in sewing, the other 2 have moved on to sports and boys. lol
