Don't feel bad. I don't know how I ended up with as many sewing machines as I have now either.
1)My New Home is my very first sewing machine. My husband, who was my boyfriend at that time, bought it for me because the one I was using, an Elna, got given away right under me by his father to my husband's sister-in-law. The Elna belonged to my husband's mother who had passed away in 1988 before I met my husband. His father did not realize I was using it off and on though and he did not think to ask either.
2)I bought a Babylock ProLine because the repair man that I took my New Home to tune up broke it. The New Home still works but I can't use the stretch stitches.
3)I bought a Brothers Innovis NX400Q, I think that is its full name, used from a trustee LQS owner where I was taking a woolies applique quilt class from. I had to buy it because my Babylock does not sew a blanket stitch. I needed it to do this quilt. Plus my other two machines were more a general sewing machine. I now am totally hooked on quilting so I decided I need a machine designed to quilt.
4)I have an old Singer. My mother had trouble sewing on it so she gave it to me. It was because this machine only sews zig zag. She was trying to sew a straight seam. I can't totally blame her. My sister bought it at a garage sale for her and nobody told her. My mother can't read English. My sister, who doesn't sew, never removed the cover and did not know specialty sewing machines were made.
5)Bernina 8 Series 820 model with the quilting frame. Hopefully this will be the last I will ever buy. I could not get my Brothers uneven stitching fixed. It sews all the other fancy stitches look mutated. I couldn't even do FMQ with it.
I keep my New Home for nostalgia. The Babylock I take with me to classes and quilting bees. I am clumsy so I figured I would rather drop an older one than a newer one. Eventually I will get my Brothers fixed because it has a side cutter serger foot. The Singer sews great zig zag stitches. I just don't know when I will need it.
