Half Square Triangle Solid Granny Square

Crochet lovers, have I got a new pattern for you called the Half Square Triangle Solid Granny Square. It’s perfect for experienced crocheters who want to add some unique color patterns to their projects.

I am a big fan of granny squares, and this pattern is a great way to use up scraps of yarn. This pattern is a twist on the solid classic granny, yet the basic method is easy to follow, and it turns out a beautiful square.

This is a fun and easy pattern that can be used to make a variety of things. You will need basic knowledge of basic crochet stitches, including single crochet, chain stitch, and double crochet.

I have used this method on the solid square version of the traditional granny. You can change this block size by adding or decreasing rounds. It is easy to make a number of squares or continue adding rounds and making a larger square.

This is perfect for so many new projects, blankets, handbags, towels, and washcloths. Currently, I am working on a blanket using fall colors and this half granny square pattern. I will be sharing that with you soon!

What is a Half Square Triangle in crochet?

The half square triangle is a quilting term that refers to quilt blocks made up of half square triangles. Essentially, it is squares made up of two triangles.  Each triangle occupies half of the square’s space.

For It is a two-tone granny square where the yarn colors are changes to form a square made from two triangular tiles of color. It is a simple square made up of two triangles.

Seamless Two-Toned Granny

Previously, I worked on figuring out a no seam solid granny square. This past year, I have expanded my sewing skills to include quilting skills. One of the more popular quilting squares is the half square triangle.

I had a goal of creating a crochet blanket to look like a quilted blanket. This pattern is starting to come together, and I will be sharing that with you when it is complete, and the directions are written. In the meantime, I had to work out how to crochet a seamless two-toned granny square.

Crochet a Half Square Granny for Beginners

In my search to create a clean looking half square granny, all I could find for half square triangle methods are squares that had seams on the side for each round. For changing yarn colors, the crochet patterns either carried the yarn through the stitches or had you cutting and weaving in the yarn for each round.

When carrying the yarn through, you can see the yarn through the stitches. It’s okay, but not ideal. However, cutting the yarn after each yarn color change was a lot of work and weaving in the yarn ends. Too much work.

Finally, a eureka moment!

A few years ago, I was trying to carry the yarn up the side of a pastel crochet blanket where I changed yarn colors. I was in a hotel room with my daughter, and I spent hours trying to figure out how make it work. Finally, my daughter said, why don’t you crochet over to the yarn color. She was able to see it, but it still took me quite a long time to figure out what she was trying to tell me.

What is Unique About this Half-Square Triangle Block?

First, I did not use the magic ring, nor does it start out with a chain 4 and a slip stitch into the first stitch to form a ring. Rather, it starts out with a chain 3 and the first stitch is worked into the third stitch from the hook.

Additionally, the yarn is not carried through the work, and I don’t have to cut the yarn with each color change. That means much less yarn ends to weave in.

This half granny triangle has different colors on the opposite corner of the square with a clean look that is easy to achieve.

Figuring out the perfect Crochet Method

We brainstormed potential different methods of how to get the look I wanted, which was a nice clean look in changing colors. Also, I didn’t want to cut the yarn and weave in ends each round. Finally, I remembered what she said to me a few years ago. Crochet back to the yarn!

So, I turned my work, which is not something you normally do for a granny square. But, when I did, I was able to use the same color of yarn I was currently using and crochet back over to the yarn I wanted to change to. I hope this makes sense.

Please make sure to carefully read the pattern, view the photos, and watch the video to help you achieve success with ease. Once you get the hang of it, it is just magic!
