One multi-size ruler offers a no-math solution for cutting both the corner triangles and the larger setting triangles that are needed when patchwork blocks are set on point.
Not just for use with our patterns ~ these rulers can be used with any diagonal set quilt design that needs corner and setting triangles. Features the same corner concept as our templates.
Available in two sizes, each ruler is small enough to handle easily and large enough to get the job done right. The small ruler is perfect for small quilts, many border designs and even many square-in-a-square designs.
Why Do We Need Diagonal Set Triangle Rulers?
Diagonal set quilts have two different half-square triangles: one for the corners and one for the setting triangles. Use this “no math” ruler to cut both triangles from the same-width strip of fabric.
a = The finished block size is calculated and includes ¼″ seam allowances.
b = The corner triangles are cut with the legs on straight grain.
c = The setting triangles that fill in the ends of the diagonal rows are cut with the hypotenuse on the straight grain.
