|Nine Patch||Uneven Nine Patch|
Free Quilt Block Pattern
I decided to add the Checkmate quilt block to the intermediate category of blocks, simply because of the number of pieces in the blocks and therefore more seams. There is nothing difficult in the making of this uneven nine patch block other than being very aware of sewing a precise quarter inch seam allowance.
The centre of this block uses the patch known as square in the square and that would be the most "difficult" patch (which is not at all). Half square triangles are used for the corners and the rest is comprised of squares and rectangles.
