I made these potholders using three fat quarters...although if you have some scraps you should be able to make it work. They finished at 14 inches. This may be a little big for potholders..but I like them. I also use them for trivets since they are quite large. I used this tutorials from Sew Happy Geek to make the double pin wheel block.
These are a great weeknight project. For those nights that you really don't have time to sew...that you know you really should be cleaning instead...but you just need to get your fix.
