Piece Accurate Seams Block After Block
Set a spot-on seam allowance in seconds and stitch with confidence—whether you're chasing a true quarter-inch, a scant quarter, or something custom for your next quilt top.
Fits your Featherweight and so much more. Designed for the Singer Featherweight 221 and 222, and right at home on most vintage Singers too—15, 66, 99, 127, 128, 185, 201, 301, 319, 401, 500, and friends.
Line It Up in Three Easy Steps
- Lower your needle tip into the hole for your desired seam width.
- Slide the Featherweight Accurate Seam Square snug against the edge of the Seam Guide.
- Fasten, raise your needle, and start sewing beautifully straight seams.
That's it. Just drop, align, tighten, and you're piecing with the kind of consistency that makes finished quilts sing.
Room to Roam Across Seam Widths
Reach for a small ruler and slide the guide to land wherever your pattern calls for—a scant quarter, a true quarter, a generous half, and plenty of stops in between. One guide, every seam allowance your quilting heart wants.
Made to Match Your Featherweight
Crafted in gorgeous 3/16" acrylic with delicate gold filigree decals chosen to echo the celtic-knot corners on your Featherweight's bed. Choose classic black or clear—the acrylic bed keeps your machine's finish scratch-free while you work. A sturdy screw and washer hold everything steady for stitch after stitch, and unscrew smoothly when it's time to tuck it away.
Made exclusively for The Singer Featherweight Shop.
Everything Travels Together
Take your setup along in the included Drawstring Bag—divided pockets keep your Seam Guide and Square cozy side by side, with a small pocket of its own for the thumb screw so nothing wanders off between projects.
