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.

The Black Hole is an easy block for construction, as it has only one quilt patch to learn -- the flying geese patch.

This quilt block is also part of the category uneven nine patch as it is constructed just the same as a nine patch, but all of the units are not the same size.
