You are a SAINT... and those girls will remember it forever! I know I couldn't have done it. I can't stand the thought of anyone touching my machines, let alone 11yos! And my stash... forget it. I guess I don't share my toys well. You are a very kind and generous soul.
Still can't figure out how you helped 11 yos to make a whole quilt in just 7 hours... sharing machines.
