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 Variable Star quilt block has many variations, living up to its name. This particular version struck me as interesting as it has two different things going for it. It uses several quarter square triangle patches and is constructed as an uneven nine patch. The centre strips that make it an uneven nine patch can omit the need for sashing strips and give visual direction while separating the patches.
