Scrappy hearts quilt squares - would be very cute "wonky" style. This tutorial includes all the math to make many different sizes of heart blocks. ----- this could be done with 9 large hearts and put a monogram in the center square.
Making Heart Blocks in Multiple Sizes (Cluck Cluck Sew)
Initially I pinned this because i liked the idea of a cross-stitch heart. But now I think the heart is WAY too big. But maybe a few 3" or 4" cross-stitch cross blocks would be fun to mix in with my little heart blocks.
