  • Quilt more, clip less—No more clipping all those dog-eared corners

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.

    Kaleidoscope Quilt

    Can't wait to use this die with the isosceles triangle die to make kaleidoscope quilts. Accuquilt makes cutting and piecing triangles together so much easier and more accurate. I also like to use the dies to cut up my scraps and make scrappy quilts.

    Triangles 3 1/2" die

    Bought this die to go with my 3 1/2" square die. My die library is HUGE! I try and buy the same size triangle and square so that I have more options to make different shapes in my quilts. And I am not good at cutting triangles much less squares with scissors or rotary cutters. They end up all wonky looking and crooked. But thanks to Accuquilt, I have PERFECT triangles and squares and can have many made at one time!

    Cutting up my scrapes

    I have a lot of small pieces of material left over from projects so I am starting to just cut them in to usable pieces. I will be making a scrape quilt with all the pieces I have been cutting from this die and others. Love scrappy quilts.

    Great with the 4 1/4 inch finished on point square

    Working on a quilt that calls for an on point square so I used the 4 1/4 inch finished on point square die and this 3 inch finished half square triangles to complete the blocks. Perfect match, perfect piecing

    The most used die in my collection

    I've used this die so much I ordered a second one. It coordinates with so many other dies for various patterns. Have used it for the connectors in several I Spy quilts, baby size pinwheel quilts, radiant star with the chisel die, and my daughter's wedding throw which had 575 of this size half square triangle along with a larger half square.. Love this die. It is indispensable.
