I have done a couple things with the Cotton Theory method, and enjoyed them both. They are a little time time consuming, but come off fairly easily. Becuase of the "theory" of how the blocks are created, you can make anything from a placemat to a king sized quilt with the same techniques - just more or larger blocks. I think reading about it is harder than doing it. My advice would be to dig up some scraps, and plan one placemat. That way you won't feel pressured to accomplish alot, but should have enough seams to get the feel of the tecnique. It is really cool that you have a finished quilt on both sides when you are done. And I really love tactile things! Here is a link to a pattern for a placemat:

Good luck, let us see what you do!
