I have 8 sewing machines!
Kenmore in a cabinet is behind one sofa, next to the buffet where my serger resides.
Singer repro is tucked between the buffet and the hutch.
A Janome, a White and another Singer are lurking behind the other couch.
A pink Kenmore and a non op Touch and Sew(haven't got round to replacing a broken gear yet), both in cabinets, reside in the garage.
Keep them all. I only have one or two set up on dinner table if I have a lot going on or my daughter wants to sew.
I used to only have one. Don't go there, because if it has to go to the shop it will seem like forever until you get it back.
I love having spares on hand.
