Monkey Wrench is another block on a nine-patch grid, and easy to make. It's a class block, with a classic look; you'll see if often in old quilts.
For a 12" finished block you'll need:
(1) 4-1/2" square light
(4) 4-1./2" light/dark Half Square Triangles (so, you'll start with 4-7/8" squares, cut in half diagonally)
(4) 2-1/2" x 4-1/2" rectangles light
(4) 2-1/2" x 4-1/2" rectangles dark
Sew a light 2-1./2" x 4-1/2" to a dark 2-1/2" x 4-1/2" rectangle along the long edge; square up to 4-1/2". Repeat to make a total of 4 of these units.
Arrange the pieces into the block:
The Monkey Wrench is a grand old block, and you can make a quilt with just this block:
Or, you can alternate it with any other block that is built on a nine-patch grid:
This is a great one to play with in Bock Fab. Have fun!
