This is the first bag I made to see if I could do it. Was disappointed in the puckering between the bottom of the pumpkin and "or treat". Not bad but still puckering. On all the other bags I did use medium weight stablizer and they turned out great. I'll take this one along for me to put any goodies I might purchase - like Disney designs - I hope. The bags are of a satin type finish but have a rubber type backing. I had thought (my first mistake) they were heavy enough not to need stablizer. I think the rubber backing made the slipping of the fabric. Just my opinion. So glad this project is completed.
