I hosted a sewing party for a few girls in American Heritage Girls to get their Explorer Sewing badge. (Genna is not an Explorer, but she wanted to do it anyway.) I was going to have 7 girls, but only 5 ended up making it. I started off with showing the parts of the machine and they drew lines from the part names to the part on their diagram of a sewing machine. Then I demonstrated how to thread the machine, wind the bobbin, and thread the bobbin. Each girl got a turn to do each of those once. Then they each practiced on a piece of paper following some lines that bent and curved without thread.
For their requirements, they had to complete two simple projects. The ones I chose were making a small simple doll from felt and a night shirt from a big t-shirt. The girls are wearing their nightshirts in the pictures. I chose those projects because I had a lot of girls to help and I knew there needed to be a lot of room for error. Wavy lines were a common theme!
