Tackle equilateral triangle quilts with this GO! Equilateral Triangle-4 1/2" Sides (4 1/4" Finished) die. Use this die with the GO! Baby, GO!, GO! Big, and Studio fabric cutters to cut multiple pieces of fabric at once. The triangular shape created by this die is an excellent alternative to simple patchwork.

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.

    Seven Sisters Quilt

    I'm excited to use this die to make a Seven Sisters quilt and a scrappy pyramid quilt and so much more. I find triangles difficult to cut out and Accuquilt makes it so easy. Pieces also fit together so much better. I love my Go Cutter.

    Pyramid Power

    I bought this die so that I could make the Majestic Pyramids Quilt. I haven't been able to start it yet as I am still working on the Twirling Stars Quilt that features the 4 1/2" Half Hexagon die. If the Equilateral Triangle die is as easy to use as the rest of the Go! dies, than the Majestic Pyramids Quilt should be a snap to make. I am really looking forward to making this quilt!

    Bought this piece to use with the hexagon. It works well on its own, too. Happy with my purchase

    Equaliterial Triangle

    I love this. The triangles are so easy to cut and are so easy to assemble.

  • David · 5/11/2017

    Super product well worth having

    I really like using this die for piecing work especially when making cushion covers. The design is stunning and the colour combinations one can use is great. A worthwhile die in your collection and so versatile.

    makes life easy

    Using this with the 4-1/2" hex makes a very easy quilt which looks very complicated! Fun!

    Equalateral Triangle

    I love this. I made a purse wit it and it turned out beautiful. Have lots of ideals that I want to try. Accuquilt has made my sewing so much easier because of the time it saves me cutting out..

  • David · 3/24/2017

    Great Triangle to use in various projects

    I really like this 4.25 inch finished triangle as it is great for using as an applique on cushion covers and on patchwork bags. It is a lovely size and really looks well positioned on a cushion or bag using a brightly coloured fabric - use either as a centre piece or in sets of four.

  • Joanne · 3/20/2017

    I think this will make interesting borders

    I bought this die and the same sized half hex die. I have some ideas that these might make sone very interesting borders. Anxious to try this out!

    Equilateral Triangle

    When i first ordered this I didn't know how I was going to like it if it was going to be hard to figure out or what!
    But once I had it all layed out and started changing the colors around I found just how flexable this would be.
    It goes without saying I loved the way my first quilt turned out ,this is actually user freindly once you see the whole picture.
    I made the first quilt without a patteren and love the way it turned out!
