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.

    Doesn't play well with the Studio Die Cutter

    I wouldn't recommend buying GO dies for use on the Studio they just don't seem to have enough strength to cut efficiently. This one worked reasonably well without butchering the fabric edges too much but the GO Rag Circle is just too hard to use even boosting the height of the die with a piece of cardboard under the adapter sheet it would only cut 2 pieces of fabric. The dies slip constantly on the adapter sheet as there is nothing for the two surfaces to grip together - disappointing.

    Great way to start curved piecing

    I can't imagine trying to make a clamshell quilt without this die. The notches are so incredibly helpful! The look of clamshell quilts is so great, but the cutting and piecing is fairly time consuming. This die makes the whole thing go so much quicker. Love it!

    looked great

    I will not use it cut out queen size and when I downloaded the pattern and it called to use glue etc. I am using another die on the fabric, my give the die to a quilting friend I don't think I use it.

    Quick clamshells

    This die works really well. The pieces are accurate with notches that make piecing easy. The curves on these large clamshells are gentle and don't present problems. Since the pieces are large, a quilt with traditional piecing goes together very fast. I am going to use circular feathers for the actual quilting. I am using the fabric remnants from cutting the large clamshells make a matching pillow with the smaller clamshell die. I recommend this die for those people who want to try curved piecing.

    Great die

    Have always wanted to make a clamshell lap quilt, but did not want to cut.
    It is great to have a GO die to make life easier!

  • Lori · 10/15/2015

    Love the looks of this die.

    I really liked the looks of this die so I purchased it. I hope it won't be hard to sew these together. I will have to see what patterns are available to go with this.

    Great Product

    Attended a large class on making the clamshell. Everyone was supposed to download the Craftsy pattern and use it. Many of us chose to use the Accuquilt method. It worked beautifully. I used the Craftsy outside pattern pieces so I didn't have to chop off the quilt, and cut the actual clamshell with Accuquilt. It takes about 10 yards of fabric or scraps to make a twin size quilt. One quarter yard cut can produce five, 8" clamshells. They are easy to sew together. You'll love it.
