I'm an introvert, but I really wanted to learn how to quilt. I didn't know a soul when I started my beginning class, but I had a grand time and really enjoyed everyone in the class. I've taken quite a few classes now & had a great time at all of them. I made a good friend there and we took several more together & even "campaigned" with former classmates to get the minimum signed up so the class would make. I enjoy them more if there are maybe half a dozen people rather than twelve or fifteen, but also know it is better for my teacher and the shop than when just the minimum sign up. If your friend's friend really want to do this she'll come without someone to "hold her hand."
