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 Propeller quilt block can be used as a starter block for beginner quilters, because it contains only simple shapes -- the square and the most commonly used shape (other than the square) -- the half square triangle.

For those who like easy math, this quilt block is designed as a 10" block rather then the more commonly used 12" blocks. However, I have included measurements for a 7 1/2" block as well as a smaller 5" block, so you have your choice. The quilt block is constructed as an uneven nine patch as all rows are not identical in size.
