Heart quilt blocks are fun to create all-year long, but especially fun around Valentine's Day. You can make them any size, but here is a formula for creating nice proportions, using a 6 ½” block for an example (in the video we make a 9" block): -Your main heart pieces should be rectangles: 6 ½” x 3 ½” (A x B) -The bottom background pieces should be squares: 3 ½” x 3 ½” (B X B) -The top background pieces should also be squares: 1 ½” x 1 ½” (B-½”) ÷ 2 | Pfaff North America
