I took a class for Fun and Done and it's easy to sew but time consuming cutting the fabric and batting. I bought the ruler set and it was much easier using the correct tools. The ruler provides the exact edge width to line up the batting. The ladies that did not buy the ruler set to start with, did after seeing how much easier it was for me to use it. I used poly batting, Fairfield Traditional. I had a lot I wanted to use up and was very pleased with the results.
