Old Ironsides is my 1935 Singer 15-91. Mostly I have just done FMQ on her. The last couple of days though, I have been piecing quilt blocks as I already had a bunch of bobbins loaded with white thread. Can I just say- THAT THING ROCKS! I am getting great stitches and it just keeps going and going. My grampa would be so proud to see me working on one of his beloved machines. It has been alot of fun working with the old gal. I can't wait to do some more on her!
