One idea was to hide a tiny heart and in the miasma of the patchwork, kind of like an I Spy game. But a small heart didn't feel right, either, because there is nothing small about our kids. They laugh often, give big hugs, run like puppies (still), and tend to be very loud when displeased (oy). These kids of ours needed a big heart.
As luck would have it, there was one final student who had yet to work on the quilt:
Even though this heart of ours wouldn't be displayed in full view for everyone to see, it would be front and center on the back of our quilt.
Unable to miss it. Loud even when quiet. Just like our kids.
