I use the 1/4" foot that I bought for my 70's Sears Kenmore machine. I also use my "Little Foot" that I bought for the featherweight. The featherweight is a short shank machine and most short shank feet will fit it. My 70's Sears Kenmore is a short shank and the feet from it are interchangeable with my featherweight. Haven't tried it, but I think the walking foot that I bought for my Kenmore will work on the featherweight. See
