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.

    Great Triangle to use in various projects

    I really like this 4.25 inch finished triangle as it is great for using as an applique on cushion covers and on patchwork bags. It is a lovely size and really looks well positioned on a cushion or bag using a brightly coloured fabric - use either as a centre piece or in sets of four.

    I think this will make interesting borders

    I bought this die and the same sized half hex die. I have some ideas that these might make sone very interesting borders. Anxious to try this out!

    Equilateral Triangle

    When i first ordered this I didn't know how I was going to like it if it was going to be hard to figure out or what!
    But once I had it all layed out and started changing the colors around I found just how flexable this would be.
    It goes without saying I loved the way my first quilt turned out ,this is actually user freindly once you see the whole picture.
    I made the first quilt without a patteren and love the way it turned out!

    Equilateral triangle die

    I love my new equilateral triangle die cutter. It is so easy to use with the side triangles to match them up... my new quilt idea is so much fun... can't wait to buy the hexagon to use on another quilt... love the corners being dog eared also...

  • Carmela · 12/17/2016


    I love triangles and can't wait to make the triangle quilt on the Accuquilt website.
    It looks easy enough, but just have to find the right fabric I want to use!

    Notches Truly Help Sewing Easy

    It was so easy to sew the pieces using the notches to match the pieces

  • Sandy · 11/20/2016


    I was really apprehensive about making an equilateral triangle quilt as the background for my first great granddaughter's baby quilt considering all the bias I would be working with. But making sure I cut on the length of the grain and used the little tabs on the triangle made it such a breeze. I love AccuQuilt. It is the best thing since sliced white bread.

  • Diane · 11/10/2016


    This triangle fits the large hexagon shape like a glove and together create a quilt design of hexagons surrounded with a 6 sided star.

    Great Die To Use With Half Hex

    I am amazed how accurate my blocks are when I use this die with my half hexagon cutting die. You will love using it.

    Triangle quilt

    I'm making a baby quilt and I had the pieces cut out and sewn together in two days. A real time saver!
