I have a bolt of white cotton fabric. It is heavier than quilting cotton but not as heavy as canvas. I figured I could use it as backing for a quilt. With that intent I sewed some of it to a piece of similar weight colorful bird fabric in a size appropriate for the back of a quilt I was designing. I changed my mind, made a duplicate of the back and sandwiched them together on the frame for a small quilt.
Maybe it was because I had a blank canvas or maybe I have reached the comfort point on the learning curve. I had no: machine trouble, design trouble, coordination problems (well, OK, a few) at all. Essentially I felt the most at ease with this process as I have yet.
My log documents 137 hours on the machine. I thought I would need hundreds before I reached this point. Yippee for me.
