Equilateral triangle quilts explained

Equilateral triangles are triangles in which all three angles of the triangle measure 60 degrees and all three sides measure the same length.  Six equilateral triangles can be pieced together to create a hexagon, offering even more opportunities to use this shape in quilting projects.

The simplicity of this shape lends itself to a variety of quilt designs, and piecing an equilateral triangle quilt is as easy as sewing a straight line! In addition to the ease of sewing these blocks, there are a variety of time-saving techniques for cutting the equilateral triangle pieces for your quilt. Equilateral triangles do have bias edges that can stretch out of shape, so remember to take care when handling your pre-cut pieces.

Cutting equilateral triangle pieces

One method of cutting equilateral triangle pieces is to use a cutting machine and template such as the Accuquilt Go! Cutting system which features equilateral triangle dies in a variety of sizes. By using this system, you can quickly and easily cut up to 6 equilateral triangles at a time. In addition, the edges of the triangles are cut to make for perfect piecing.

There are also a variety of equilateral triangle templates and rulers available for ease in cutting these shapes. Marti Michell and Creative Grids both feature 60 degree triangle rulers in a variety of sizes. Some templates for equilateral triangles feature a trimmed edge on the corner tips which makes sewing the triangles together very easy. For equilateral triangle sewing without trimmed corner tips, just remember to always overlap edges by 1/4″.

If you don’t have access to a specialty cutting system, template or ruler, you can always create your own equilateral triangles by using the 60 degree mark on your ruler. Cut strips to your desired height, then use the 60 degree line to make your triangle cuts.

Note: When using an equilateral triangle quilt pattern or design, be sure to use the specified method for cutting your triangles.
