I have 4, a 1920's treadle, a 221 FW, a Viking, a Kenmore and a Singer 301. The 301 is in a beautiful cabinet and I love to sew on it. I has a beautiful stitch and it sit next to to a large window to my back yard... My 221 and Viking go with me to classes and quilt retreats. I learn a long time ago to always have a backup. A lady at a retreat was lucky that I had a spare machine in my car, hers' broke and we were 1 1/2 hrs up the mountains...
I have given away 4 machines that did not mean much to me but were very much needed by others...
