I had an old (1983) basic Sears Kenmore that I was using to construct garments. My husband proposed buying me a new machine for my birthday and I chose a machine for garment making (a Huskvarna Lily 535 - a great machine). After that I started quilting and I wanted different features that the Lily didn't have - specifically needle up/down and a larger harp. So I got a Janome 6600. Then I got a vintage Singer 66, then a vintage Singer 115 ... and Sunday I'm picking up the new member of the herd!!
So ... 6 machines!
I won't give up my Husky ... I like that machine too much. I'd be willing to part with the Kenmore. The vintage machines will of course remain.
