Arranging triangles in colorful combinations makes for a fun quilt design. With the GO! Half Square Triangle-1 1/4" Finished Square die, it's easy. For versatility, make your half square triangles (HST) into a 1 1/4" square simply by sewing two together. You could also use two triangles to build cornerstones in borders by using a GO! Strip cutter die. There are a limitless number of quilting patterns that include the HST. Use your AccuQuilt Fabric Cutter to make cutting these small triangles a breeze. You'll get precisely cut lines through multiple layers of fabric, which saves you time and makes piecing easier. The GO! Half Square Triangle-1 1/4" die can also be found with three other dies, a cutting mat, instructional videos, and a bonus pattern booklet the GO! Qube 10" Companion Set-Corners. The set expands your quilt blocks in the GO! Qube Mix & Match 10" Block from 72 to 144 or more. 

AQ Cutting Mat Required: GO! Cutting Mat, 10 in. x 10 in. (25.4 cm x 25.4 cm)

How to Die Cut 1 1/4" Finished Half Square Triangles:

For best cutting results, position fabric on the lengthwise grain (straight of grain) as it goes under the roller.

  • Cut a 4 3/4" strip across the width of fabric. Fanfold into 4 3/4" widths. Place on selected blade and cut. Cut 64 half square triangles across the width of fabric. One yard of 40" wide fabric cuts 448 half square triangles.

AccuQuilt Benefits: 

  • Cut so much more fabric in less time. 
  • Get accurate cuts every time -- No slipping rulers or mistakes
  • Easiest to use -- Simply place die on cutter, then fabric and cutting mat on top
  • 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

Die Tips: 

  • With some fabrics, after cutting, a thread or two will remain where die blades meet. Snip threads with scissors. 
  • Blades on some dies are positioned at an angle.  Align fabric to edge of shape, not edge of die board. 
  • 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. 


Use adhesive roller or die pick to clean lint and thread from dies. Die blades never need to be sharpened.
