Abbieb,
On the needle plate on the sew4less site the feeddog slots don't match yours/ ones on Sears site. This plate probably won't fit your machine.
Your machine may not have come with a straight stitch plate. Usually interchangeable plates aren't held on with screws. They "clip" on by various methods. The Sears site shows the plate as held on by screws.
Hope this helps,
Cathy

I think for the most part I have it working pretty well - although this is my first ever sewing machine so I'm certainly no expert!
I've been reading about the advantages of using a straight stitch plate, but from looking on searspartsdirect.com, it seems there is not one available for my particular machine. However, it looks like SS plate #15280 (
http://www.sew4less.com/product/5943...traight_Stitch) is similar in size and shape to the ZZ plate that came with my machine (

Has anyone used plate 15280 on a Kenmore zigzag machine? I also read about taping an index card over the plate to cover the wider ZZ hole - is that a workable DIY option?
Thanks for your help!
