I stitched the ditch(sort of) on a Queen size quilt on my humble Kenmore with a 7 1/2" throat. This was a quilt made for a basset hound rescue auction before I really knew anything about quilting. A friend had some blocks already cut and she asked if I could put a quilt together. In my ignorant bliss I said I guessed I could. Knowing what I know now I probably wouldn't have attempted quilting it on that machine. I did get it done-even made matching shams. It was won by a friend who uses it her spare bedroom. I cross my fingers every day that she never has to wash it...LOL.
