Hi all! This is my first post in the vintage section as I recently became the owner of an old Sears Kenmore 158.841.

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!
