Nine Patch Uneven Nine Patch
The Uneven Nine Patch style of quilt block is so named because not all of the nine individual patches are the same size as is the case in a regular nine patch quilt block. This style of quilt block is often used in 10" quilt block to make the math easier, but you will find this construction method in many other quilt blocks as well.

Free Quilt Block Pattern

The Square and Half Square quilt block is technically a five patch design -- (as it is created using a 5 x 5 grid), but it will be constructed as an uneven nine patch for ease in the sewing process.

The name of this quilt block is a bit "lacking" I would say, as it alludes to the block being designed using only squares and half square triangles. However, there are a few quarter square triangles as well, and those patches are what forms the star in the centre of the block.

Although this block may look intimidating, it is quite easy to construct, as long as you pay close attention to sewing an accurate quarter inch seam allowance. Enjoy!
