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 Year's Favorite quilt block is a four patch that is a perfect choice for a beginner quilter. It contains only the two most commonly used patches -- the square and the half square triangle.
When I chose the fabrics for this block, I deviated from the "norm", in that I used the focus fabric as the background. Since my background fabric is dark, the lighter fabrics draw your eye into the pinwheels.
Two very different quilts evolve when you choose to set the blocks side by side or on point as shown in the sample quilts illustrated.
