Double Monkey Wrench Block

Double Monkey Wrench Block

DIFFICULTY LEVEL ‣ BEGINNER

FINISHED BLOCK SIZE: 9″ X 9″

Double Monkey Wrench is a great practice block for beginners, as it uses squares, half-square triangles, and strip sets. A variation of the Shoo Fly block, it differs in that there are bars surrounding the center square rather than other squares. You may see this block referred to by such names as Churn Dash, Hens and Chickens, Monkey Wrench, Hole in the Barn Door, and a host of others.
