I think your quilts are soooo cute. I am glad you found the thread that works for you, I have been having trouble with my thread bunching up on the backs of my quilting too. It is very frustrating. I make quilted tote bags, and I don't check the back after every row I sew, so when it happens, I have rows to take out. I quilt the fabric, and then I make the totes. It takes five hours to quilt it and five hours to make the totes, and that is when I don't have to take any rows out. Great job, and thank you for sharing.
