Thanks so much for all the information -- and for replying so FAST. Actually, people have been giving me lots of old bobbins which don't fit in their machines anymore. And all the while I thought I was really lucky. I have two machines -- a Baby Lock Model BL 1556 and a Husqvarna Emerald 118. I will start googling today and know I will hit paydirt at Joanne's where I bought my Husqvarna.
