I have always felt guilty of how many I have, but now, I feel right in the group.
Non-working, just need servicing, 1 old cast iron Remington, a treadle--use all the time 2 featherweights, an older Singer, Bernina 180--had to devote a special computer with Windows 98 for its embroider because Bernina does not have computer support past that, Viking Designer 1, Pfaff quilter, 2 sergers. Each machine does specific things with special attachments that the other machine's don't have, such as gathering, turning a 1/4" hem, does well with invisible thread, 3 thread serger, 4 thread serger. Wouldn't get rid of any of them.
