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
  • Easiest to use—Simply place die on cutter, then fabric and cutting mat on top
  • Get accurate cuts every time—No slipping rulers or mistakes
  • Create quilts you never thought you would—AccuQuilt makes cutting curvy classic quilt patterns a snap
  • 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.

    I use them all

    I use all of the dies. I have RA and cannot use a roller cutter. The moe the dies the better.

    I bought this templet die for my Storm at Sea Quilt. Makes piecing so much faster & ACURITE. The ONLY way to go. (GO-BABY)

  • Cindy · 3/29/2015

    excellent such a time saver

    Wow. why didn't I buy this sooner. I am into scrappy quilts and HST were always such a time consuming cutting task. If you lay your fabric together correctly when you cut you can have your pairs ready to sew right off the die. I am in love with AccuQuilt cutting dies.

  • Debra · 2/21/2015

    Wow! What a time saver!

    The HST dies where the last ones I bought. I thought that making HST with my paper piecing method was the best. I am making a feathered star that has 80 HST and this die was just what I needed.
    I love Accuquilt!

  • Irene · 2/18/2015

    Love it

    I made 96 flying geese with a traditional method. This die came in the mail and I loved using it to make more flying geese and look forward to using it in other ways.

  • Carolyn · 1/29/2015

    Die needed for Storm at Sea

    Fell in love with Storm at Sea, the plan to have my husband cut out the pieces while I'm at work. I am confident they will be perfect! Opps, hope he doesn't see this before I ask him.
