Block of the Month - Half Square Triangles


Two easy blocks this month, or not really blocks, but arrangements of half square triangles.

The row above last month's pinwheels is made with 1½ inch half square triangles, that finish at one inch. When put together, the finished long block should measure 2½ x 24½.

The other row we're doing this month is above the pink triangles of the sunflower block, and those are made with 2½ triangles, that finish at two inches. The finished block should measure 4½ x 12½.


My preferred method of making half square triangles is to go print the free papers online. You may use any method you like as long as you end up with the triangle sizes you heed.

Here's the link to print the pages:

Important! Please m ake sure that the options on your print dialog box that might say something like "fit to page" or "shrink to fit" are NOT checked, before you click print.

Some people call this block "broken dishes." You can choose any colors you prefer, but make sure they look nice above the pinwheel blocks you made last month. You need 48 half square triangles to make this.

This arrangement is almost the same, but most folks see windmills first, three of them. You'll need twelve half square triangles for this block.

I'm going to assume that people attempting this block of the month project already know how to paper piece.

The site where we're printing the half square triangle paper has some great tips for paper piecing:

What will YOUR blocks look like?
