Let me see, I have a Viking SE embroidery, Brother 4000d emboridery, a Pfaff 7570 (an older embroidery machine) that I piece with, 7 Featherweights, 2 singer 301s, my MILs machine and a Pfaff serger. I think that is it unless I happen to run in to another that I can't live without. You NEVER have to many!!! They say, the one that dies with the most wins!! LOL
