Craftsy. The class included how to do pockets and zippers.
This is my reversible tote:
This was my Sunday project. The zipper was easy, once I caught on where the teacher was placing the fabric. I got more confused by the how to sew the bag because it was lined. Which sides you sew, and which you don't, because it is designed inside out. The instructor did use an interesting technique with the zipper. She didn't have us use pins to hold the zipper in place. We used glue from a glue stick instead. (Yes, a school glue stick). I've heard people feel challenged by zippers.
I still want to do a lunch bag. After looking at a blog post, I plan to take a pair of sleeper pants and try to replicate them too. Not often you see a person ironing a pair of sleeper pants, but they were wrinkled.
