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.

Star in Square

Free Quilt Block Pattern

The Star in Square quilt block is a five patch block featuring lots of half square triangles and also quarter square triangles. There are a few squares thrown in for good measure, but overall this is a star block featuring lots of points. It's a good choice for the learning experience of practicing up on your triangle patches and is a nice change from the usual selections for quilters who are beginning their journey in quiltmaking.

Even though this block is a five patch, I choose to sew it as an uneven nine patch for the simple reason that I like working in "chunks" rather than in rows. You can choose your preferred method and the end result will still be a stunning block.

The sample quilts illustrated use the two standard settings -- a quilt with blocks side by side (and separated by sashing strips) and a quilt set on point with setting triangles and blank squares to showcase your quilting skills. All in all, this is a lovely block for your collection.
