The vintage Montgomery Wards (made by Juki) was a Salvation Army rescue. $13. My Elna has a serpentine stitch that I've used for a lot of things, but the machine is only straight stitching as it curves back and forth. The MW serpentine curves back and forth with a small zigzag almost like a satin stitch so it's much more impressive. Varigated thread? I'm FMQ with a red/white varigated. It's a thought, but I don't want to detract from the appliqued panel. I used satin stitch and buttonhole stitch both on the panel. The Elna does a wonderful satin stitch. The MW didn't need a walking foot when I did the Jewel Box, but if it does, I can use the Elna's which is actually a Janome as both the Elna and the MW are short shank machines.
Thank you, everyone. Sooner or later, I'll post a picture.
