I had to laugh when I read the title to your post. The kids in my sewing class did a community service project over the holidays that entailed sewing blankets for kids using minky on one side and some other slippery than an eel fabric on the other side. I was the designated seam ripper goddess while they struggled with bunching and uneven borders. We finally found pinning profusely in sections, starting in the center of the fabric, worked wonders and ended up making 15 presentable blankets for donation. Now one of the girls is making a dress out a very slinky spun polyester and she made the comment that after that minky, this was going to be a piece of cake!!
