Well, I have 4. I still have my origonal machine that my parents bought me (used) in high school. It's a 50 yr old Viking with cams. I still use it on occaision, and keep it around as a backup and for something to teach my kids on. Then I got a new Viking in 2005 that I love it's a "Scandinavia 200" Just a few decorative stitches, but it has done everything I needed it to do for the last 8 years, and I have my Elna serger that I've had since 1996, and I just got a Babylock "Crown Jewel" that I love!
If I had it my way I would like to add an embroydery machine! And maybe one day an antique one with the origonal treadle, but if that never happens it's no big deal.
So apparently my ideal sewing machine collection would include 6 machines. LOL! And here I think I'm just so "basic" as I really only think of my "Scandinavia" and serger, but I guess the other 2 are sewing machines too huh? Though the old Viking spends most of it's days in the case unused. Perhaps it's time for more sewing lessons. But my 12 yr old DD is afraid of sewing her fingers. Hehe, gotta get her to practice lots to get over the fear.
