At long last. I think I am done with Cell Blocks (7 x 17), but I am not really sure. I had some problems with the machine thread . The machine kept making long floats on the surface and then these would get caught in the presser foot and make a big mess. I cleaned everything out, changed the needle and so on, but kept having the problem. I got tired of fighting it, so I am through for now. I will just look at it for awhile and see if I want to make changes.
