I love using tumblers for quick quilts you don't need to think too much about while sewing together. I realized that I could make tumblers out of 5" squares by cutting off an inch on the right and left sides, at an angle of course. That makes the tumbler 3" at top and 5" at the bottom. I haven't done this with other sized squares yet, but I'm sure it would be fairly easy to figure out. (For those of you who, like me, are hesitant to spend money on templates that have limited uses)
