I agree Anael, that block should be renamed Trouble in Kansas, tried 5 times (remember I don't give up easily) to draw that block up but either my ruler was off or I was holding the pencil wrong, or I wasn't wearing my glasses
but one square was always smaller than the rest... SOOOOOOO I decided to cut all my pieces 1/2 inch larger and cut them down to size, worked perfectly
but gosh 3/4 inch HST
