I have 2 4-thread sergers, a Juki then I found a Bernina at a too-good-of-a-price-to-pass-up @ Good Will, I have a Singer Industrial because I sew a lot of thick chenilles for baby bibs, then a Janome Memory Craft 4400, a Necchi Royal Series that I used before I purchased my Janome (which I keep just in case my Janome needs to go in the shop). I have an awesome older Brother that I keep a ruffling foot on but has so many wonderful stitches that I can't bear to get rid of... a Featherweight of my Mothers, and last but not least... a Bernina 1260 that I haven't gotten to know yet which I found on CraigsList in another state. OH.. one more machine, the one my Father purchased for me for Christmas in 1975, 4 months before he was killed in a car accident.
I believe that is all, but I should check our bonus room.. after all, I am the one that found a serger in my closet that I had forgotten about.
I just had rather keep them all than sell them, because you never know when you need a back-up (or two, or three)
