Nine patch quilt blocks are numerous and likewise, the "sister" block type -- the Uneven Nine Patch. Both can be simple or challenging, depending on the number of pieces in each quilt patch.

Nine patch blocks are comprised of nine units, laid out in three rows of three patches. This is probably the most commonly used type of quilt block made.

The All Hallows quilt block is the perfect choice for Halloween and so naturally, I used the obvious colour scheme for this nine patch block. And .. I'm always a sucker for a pinwheel block.

The quilt block features lots of half square triangles and flying geese units -- the first two patches that you learn as a beginner quilter.

Depending on how you lay out the completed blocks, you might see secondary patterns emerging when you place the blocks side by side or separate them with sashing.
