Each guide 3/16" thickness, and the acrylic helps keep the bed of the machine protected from scratches. Featuring the darling gold decals on a black or clear surface to match the classic Featherweight design. Includes screw and washer for seam guide stability and consistent, accurate seams (yet easy to unscrew as needed). Using a small ruler, measure and slide the guide to obtain a wide range of seam allowance preferences -- from a scant quarter inch (1/4") seam, a true quarter inch seam, and more!
Fits Featherweights and many other vintage Singer sewing machines
