Mock Basket Weave Quilt Block Layout If you count the squares across in this quilt layout, you'll find that there are eleven rows of squares, instead of the ten you'd expect for a four-patch quilt block.
Take a look at that last row on the right. It's half of a block, and was added for symmetry, to make the first vertical row of squares match the last vertical row. It isn't necessary to arrange your blocks like that -- it's just an option to consider.
