  • 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.

    Fast easy cutting curves

    I have always stayed away from blocks with curves.

    This die produces great cut curves and make sewing so much easier

    Tricky at first but fun outcome

    These were TRICKY to get into a sewing "groove" but after a few rows and some practice clamshells my wall quilt turned out awesome! Not really for beginning quilters. It worked well with a charm pack but there is quite a bit of waste using a charm pack. I had to watch a few YouTube videos to figure out how to sew these together but even those were just ok--good to watch but not the best out there. The best learning tool was to just dive in with some practice shells and PRESS after sewing EVERY.SINGLE.SHELL--vertical seams open and curved seams downward--time consuming but worth the outcome and important to get proper shape. USE the notches to line up seams and half-way points....I tried to fudge it at first but eventually the notches became my best friend.

    One of My Favorites

    The clam shell die is one of my favorite dies and I'm always on the lookout for new ways to use this fun shape. I've had my AccuQuilt GO since it was introduced, well a few months after; and of all the dies I've collected the clam shell has become one of my go to shapes when I need something distinct. True it isn't the easiest shape to sew, but with patience it can really make your project shine. I love it!

    Best way to make a Clamshell Quilt

    I would not attempt to make a Clamshell Quilt without this die. The die gives you pieces that are all cut the same and the notches make it so easy to line up and sew the clamshells together.

    Valentine wall quilt

    Used this to cut up a valentine charm pack and it took just a few minutes! I'm hooked!

  • Vivian · 10/15/2015


    I would like to try this quilt

  • Lori · 10/15/2015

    Such a cute die!

    I purchased the larger clam die and saw this one too. It is so cute. Use can use charm squares with it so that is a plus. I haven't used either one yet but I am eager to try them.

    My teenage granddaughters love the quilt I made for them!
    The cuts are so accurate and it was fun to use them!
