HST = Half Square Triangle

Half Square Triangles (HST) have straight grain on the two short sides. Quarter Square Triangles (QST) have straight grain on the long side.

About the sizes

All Inklingo shapes are named with the finished size (minus the seam allowances).

Most patterns list the finished size of the shapes. If the finished size is not listed, you can usually tell the size by looking at adjoining squares and other shapes without doing the math.

You need this shape collection if a pattern requires you to cut strips 1.25 to 4 inches into squares and then cut the triangles. With traditional methods, designers add 7/8 (which is just an approximation) to get the width of the strip, so in some patterns:

  • Cut 0.375-inch HST from 1.25-inch squares
  • Cut 2.125-inch HST from 3-inch squares
  • Cut 3.125-inch HST from 4-inch squares

7/8 = 0.875
These sizes of HST are very common because the strips are easy measurements to rotary cut. There is an article about this on the All About Inklingo blog.

Inklingo Triangle Quilt by Sara Natwick

“I’ve successfully been working on two quilts that happen to both be made of HST only. I loved being able to print on only one fabric, sew the seams, and then cut them apart. My scrappy quilt, I printed a large page of light triangles, then cut them in thirds so that I could match each fabric with three different darks.”  Sara in Colorado (Sara saw this design in a Fons & Porter book.)
