For May’s block:
Use 6″ squares, 2 of a red print, and 2 solid white.
Make a simple 4 patch with the prints and the white. Cut one inch from center on all four sides, rearrange as shown in video and sew back together.
Follow the directions in the Missouri Star’s Disappearing Four Patch tutorial here:
By using 6 inch squares you will wind up with a 10″ square when done.
