I wanted to scan the pattern I used to show you what it looked like. Well, I searched and searched and couldn't find it. Finally, I decided to look for it in the place where it's supposed to be and there it was! Which just goes to show you, if you want to find something, don't put it away. This is the pattern, Simplicity 9128 from 1970.
