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 Castles in Spain quilt block is an uneven nine patch design containing half square triangles and quarter square triangles in an unusual construction, but certainly not difficult. The end result is very striking.

This quilt block would be a good choice for a beginner quilter as it deviates from the usual construction methods in many quilt blocks so the quilter gets to try a new approach to making a standard sized block.
