  • Keep the quilting ruler you already have. Attach the Half Square Triangle Addition to the edge, line up your fabric to the finished patch size, and make HSTs with no math.
  • No more adding 7/8 inch. The Addition automatically adds the exact HST seam allowance as you cut along its edge.
  • No fractions and no trimming. Use whole-number finished sizes instead of awkward ruler lines, so your half square triangles come out accurate from the start.
  • That difference matters. Using 7/8" makes sewn triangle squares oversized, so quilters often have to trim them to match the squares in their blocks. No more trimming.
  • Works with standard acrylic quilting rulers without permanent lip edges. Use one Addition with a 12 inch ruler or two with a 24 inch ruler for full-width fabric cuts.
  • Premium suction cups hold the Addition to your ruler while you cut, and release tabs make it easy to remove or reposition. Add a dab of water for a firmer hold.
  • Built-in Finger Guard helps keep your fingers farther from the rotary cutter while cutting along the Addition edge.
  • Standard rulers make you add 7/8" (0.875") to make HSTs, but the Half Square Triangle Addition lets you add the exact amount needed for HSTs: 0.854" - almost 1/32" less than 7/8".
  • Durable polycarbonate. Left-handed friendly. Made in USA.
