The half square triangle unit is probably the most commonly used patch in a quilt block -- well it is second only to the square. It is made simply with two triangles, filling up half the square each -- hence the name. Take a quick look through this website, or in any quilting magazine, and you will start to notice that this half square triangle, regardless of its size, is present in more quilts than not.

The Desert highway is a simple block using the most common quilt patches -- the square and the half square triangle. I have chosen to construct this block as an uneven nine patch, simply because I am not a fan of sewing individual rows together. However, do not hesitate to construct your block in rows if that is your preference.
The sample quilts illustrated give you some idea for how to make your own personal heirloom. Layouts shown are set on point and blocks side by side. However, don't be limited to these examples. There is no end to the way you can create your quilt.
