My daughter is four and I have a lot of extra craft stuff to use up.
I cut some card stock into post card sized pieces and cut out a bunch of hearts in some cute printed craft paper (no idea why I have a big fat pad of craft paper sitting around, but this is the second round of cards I've gotten out of it). She's glued the hearts to the paper.
I'm planning to punches holes around the edges because she LOVES lacing and let her lace around the edge and tie a bow in the corner (again, I have extra that's not being used for anything).
For the back, I think I'm going to write "LOVE, HER NAME" on the back in glue and let her glitter over it...because apparently I just love sweeping?
