Making Half Square Triangle (HST) Blocks

How to Create and Square Up an HST Quilt Block

The Traditional Method of making Half Square Triangle Blocks (HSTs) is to place a 2-7/8″ dark square right sides together with a 2-7/8″ light square. Draw a diagonal line on the back of one square. Sew 1/4″ on both sides of the line. Cut on the line and press to the dark. You will have made two blocks which measure exactly 2-1/2″ square.

My personal preference is to cut the original squares slightly too large (3″) and square up the HST to 2-1/2″ later on.

Using the 3″ squares, make the HSTs as shown. Square up to 2-1/2″ and press to the dark.

Four quilt blocks on a green cutting mat, each made from two triangles of fabric in contrasting colors and patterns, including gray, black, yellow, and orange-red prints. — You will need: (4) Gray and Orange HSTs; (4) Black and Orange HSTs; (2) Gray and Red HSTs; and (2) Black and Red HSTs.

The center of this block is put together in rows. Using the HSTs you just made and the pieces in the Assemble list, create these rows. Sew them as shown, pressing the block seams in the row in opposite directions. Press the row seams down. This helps the row seams nest and lay flat when sewn together. The center should measure 8-1/2″ × 12-1/2″.

Colorful quilt pieces arranged on a green cutting mat, featuring rectangles and triangles in shades of gray, yellow, red, and black, with a ruler grid visible in the background.

Create two side borders like the ones shown, pressing the HST seam up. Sew the borders on the block, press to the border, and you are done!

A quilt block in progress on a green cutting mat, featuring gray background strips, yellow and orange triangle shapes at the top, dark blue sections in the middle, and orange triangles at the bottom corners.

A quilt block featuring jagged shapes in black and yellow, with orange triangles in the bottom corners, set against a gray, patterned background with grid lines. A small black square sits near the upper right. — II like the Tucker Trimmer ruler because you can square up so many different sizes. Notice how the diagonal line on the ruler matches up with the diagonal seams in the quilt.
