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.

    Clamshell 4"

    When I ordered the Go! Big, the Clamshell 4" was the second die I ordered. I love the shape of it and I think the possibilities for quilts and other projects are endless. I tried it on a scrap and, of course, it worked perfectly. I can't wait to get started on a project!

    clamshell 4"

    I add to my collection. I haven't use it not yet but I know it will be great.

  • Diane · 1/19/2015

    Time saver

    I ordered this online to make a baby quilt for a friend. She really wanted a clamshell quilt but I dreaded the cutting. Then I got my Go! for Christmas and ordered this die. It even has tabs to line them up, perfect! This will cut my time cutting and piecing so I can get the quilt done before her baby shower, yay!

  • Shirley · 1/16/2015


    Well, I got the clam shell die for those really irregular pieces of scrap material that the other dies may not work with. I have many years of scraps to work thru. So, the "Go Baby" and the dies that work with are going to be my summer clean up the sewing room project....

    Pretty quilts

    This will make a really pretty quilt. I have seen some using the clam shape and I wanted to make one. I'm excited about trying it.
