Create a multitude of geometric designs and borders with this GO! Half Square Triangle-1 1/2" Finished Square die. It's compatible with the GO!, GO! Big, GO! Baby, and Studio fabric cutters. This die eliminates the hassle of scissors and rotary cutters by accurately slicing multiple pieces of fabric at once.

Use GO! dies with your GO! and GO! Baby Fabric Cutters to cut precise, accurate shapes in just seconds.

Features and Benefits:

  • Cut so much more in less time—Cut up to 6 layers of 100% cotton fabric at once

  • Save fabric with Two Tone Foam—Get more out of your fabric by placing it only over the shape you want to cut
  • Safe to use—No blades come anywhere near your fingers
  • No more math—Geometric shapes are designed with an accurate 1/4" seam allowance in the design
  • Quilt more, clip less—No more clipping all those dog-eared corners
  • Quick and easy applique—Apply fusible web to fabric prior to cutting

Storage: Organize GO! dies with AccuQuilt GO! Die Storage Rack (55115).

Care & Maintenance: Use adhesive roller to clean lint and thread from dies. After each use, with the die pick provided with the cutter, remove any threads imbedded between blades and foam. It's normal for threads to get caught where blades meet in a die. Remove with tweezers or die pick. Die blades never need to be sharpened.

Die Tips:

  • With some fabrics, after cutting, a thread or two will remain where die blades meet. Snip threads with scissors.
  • Use cutting mats that matches size of each die.
  • For best results, cut with die blades running under roller at an angle. Do not cut with blades parallel to roller.
  • Blades on some dies are positioned at an angle. Align fabric to edge of shape, not edge of die board.
  • Some dies feature specially designed corners to aid in alignment and pre-cutting.
  • For fast applique, apply fusible web to fabrics, then cut shapes with dies.
  • Use good quality fabric to reduce fabric stretch.
  • It's always a good idea to test cut one shape before cutting many shapes to ensure fabric orientation is correct.

Warranty: AccuQuilt GO! dies are guaranteed for one year.

    Fast Easy Triangles

    With this die you can cut 36 triangles at one time. Not only does it save time, but it makes the triangles accurate

    Great Die

    I have issues with my shoulders and hands, with this die and (I have the Go Baby) cutter it makes short work to get the fabric cut out, and I have more time to sew, without all the usual pain. I don't have nearly the waste of material as I did when I tried to cut with ruler and rotary, Even with the no slip stuff on the ruler, mine always slipped or my wrist would go wonky and I didn't cut straight.

    half sq tri-1 1/2 finished sq

    this little die is wonderful!! who want to cut those little pieces!!

  • Beverly · 1/6/2016

    Uniform cuts are such a breeze

    We all know that you can make quilts quicker and easier using larger shapes and strips, but I love to make small patterns, especially when making a quilt for a baby or toddler. This die makes cutting dozens of shapes so fast and easy. Saves my hands lots of strain and pain and gets me to the machine to piece much quicker resulting in fast completed projects that look truly professional.

    I needed this die to do a MQ. It is wonderful. I need over 200 hst, could not imagine doing that many without this die. Also need it for a Storm at Sea for my son's quilt.
