I taught beginning quilters for just over a year. They were terrific. I would insist that they know their sewing machine and have them bring their manual. Many times people showed up and didn't know how to thread their machines or how to fill a bobbin. I also asked if they had ever used a rotary cutter. If not, I had them show up 30 minutes early for a quick freebie lesson. Another important task was showing them how to sew a good 1/4" seam (you can put a piece of masking tape on their machine as a guide). Once they learn the basics, the teaching is a joyful experience. Try a rail fence quilt or a log cabin quilt. Check out books by Quilt in a Day or by Alex Anderson. There are books specifically for beginner. Have fun!
