What could be easier, math-wise, than a quilt block in a 10 inch size? Surprisingly, the 10" block is not the most commonly used size, (that would be the 12" block), but there are still many quilt blocks that fit into this category and here is my list of currently available patterns.

Mrs. Keller's Nine Patch

Free Quilt Block Pattern

Mrs. Keller's Nine Patch is an interesting name for this quilt block because, depending on how you look at it -- (and your colour choices for fabric) -- it contains a nine patch block in the centre (although you will really have to search for it), or the construction (as I have shown you here) is to make this quilt block as an uneven nine patch block.

This quilt block could be considered as a five patch as well, because it is made on a 5 x 5 grid. All in all, this is an easy block to construct and you have great fun with your colour choices.
