Sssshhhhh, don't tell my sister, but I kept the underbraider as I think they are neat. It works kind of like bobbin work. You stitch from the back side of the fabric. I think it works well with soutache and mini rick rack. The underbraider does
not work well with
metallic soutache, as the edges of the metal catch on the attachment. I also read
https://vintagesewingmachinesblog.wo...-underbraider/ that it will clean out your feed dogs if you use white on white.
I haven't watched this

Have fun.
