Crochet Quilt Blocks- the Half Square Triangle

Crochet quilt blocks lend themselves to unlimited creativity. These can be great for scrap projects or planned out artistic works.

Below I describe how to create your own simple geographic block, as well as some idea suggestions.

In the world of quilting the half square triangle, even using just this block, the possibilities are endless. Essentially it is simply a square that is worked with two colors. It is divided on the diagonal, creating a look of two triangles with the long ends together.

Sizes for crochet quilt blocks

Create your own design, just ensure that these blocks are the same size, or equal fractions of each other. Meaning make big and little blocks. The big block might be 10” then the little squares should be 5” so that they can all be put together equally.

Getting started with your crochet quilt blocks

To begin, create a chain the desired length of the diagonal of the square. This chain should be an odd number. Work a single crochet decrease over the 2nd and 3rd chain (need to know how to work a single decrease, check it out here), single crochet in each chain across until 2 chains are left.   Single crochet decrease over the last 2 chains, then chain 1 and turn.

All subsequent rows of this half of the square are worked the same. Work a single crochet decrease over the first two stitches, single crochet in each stitch across until 2 stitches remain, then work a single crochet decrease over the last two stitches. Repeat this until only 2 stitches remain, and then single crochet decrease these tow stitches together.

Using another color and the unused loops of the beginning chain. Work the same stitch technique of decreases on each side of the row.

The block is really just that simple. Now for some ideas. I have found plugging the term “half square triangle quilt” into a search engine, and then selecting the images option, that there is a great abundance of uses.

Some of my favorites are the Ohio Star block, Flock of Geese block, and Pinwheel blocks. The half square triangles that are created can be put together to form these larger blocks, then these blocks can be put together to create pillows, blankets, ponchos, the possibilities are only limited by imagination.
