Our guild did a Jelly Roll Race a few months ago. I had brought my Singer 301a vintage machine to sew on, not planning to do the Race. However, since there were no other projects to do, I bought one of the scrap jelly rolls and joined the Race. There were about 50 women in the room...and many kinds of sewing machines...Janome, Bernina, Brother, Singer...new and vintage. Well, guess what...my little old 1951 301 and I won the Race!! It was a blast!! The 301 takes a smaller bobbin, and I ran out twice. Luckily the lady next to me was not doing the Race, and had her Featherweight there, which takes the same bobbin as the 301. She kindly wound bobbins for me, as I only had 2 with me. Even with the changing of the bobbins we won....fun fun fun!!! :-) Says a lot for the little old vintage machines!!
