Welcome to Block 6 of this year’s block-of-the-month, Hindsight. Start by stacking the three rectangles with right sides up. Then cut the diagonal top left to bottom right (if you cut the opposite diagonal you’re block will still work but will be the mirror image):
Rearrange the triangles so that you have three unique pairings and sew each pair together along the diagonal (note the bit of overhang):
Press and lay out the three rectangles:
Arrange the rectangles so that no same fabrics are adjacent to one another:
Sew these three rectangles together and trim to 15.5″ x 15.5″ square:
Happy Quilting!
