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 - small Review by Susan
Overall Rating

Have always loved the look of clamshell quilts. This die makes it uber-simple to gut that complex shape and put a quilt together, quickly. The tabs really help line up the shapes.

Clamshell is fun! Review by Robin
Overall Rating

This die gives me the assurance of accurate piecing and takes away the fear of distortion! It makes hand and machine piecing a breeze & the clamshell design is classic & traditional - something I treasure in quilt designs!

Fun shape Review by Connie
Overall Rating

I really enjoyed using this die for raw edge applique. I was able to cut each piece out of charm squares and I used glue to adhere them to a backing before I did my applique. I will definitely be using this die alot!

I am hoping with the markings I can greatly improve my curve work. I love the look of a finished project using this die

great but tricky Review by katie
Overall Rating

It is an adorable die and the finished project looks great but if you are not familiar with curves this is not super friendly to use. The tutorial online glosses over how to start sewing them together and provides little instruction which would have been helpful. I found another tutorial online that explained assembly better. Love the die overall and would recommend the larger clam shell as a starting point but I was limited to the small one because of only having the go baby cutter.

Best die yet Review by Mary
Overall Rating

I have received my 4 inch clamshell die and very impressed. In two days part time I cut out whole lap quilt pieces and hand sewn 7 rows complete together. The notchs make it simple and fabric sews in with ease. Thank you Accuquilt. Mary

Cute shape Review by Marguerite
Overall Rating

I will have to get this. The finished effect is very cute. Curves are hard for me, but I think this die, with its markings, will help me to sew accurately. I look forward to getting and using it. I am really getting into quilting and, due to some severe neck pain issues that are aggravated by rotary cutting, I find my GO indispensable.
