I digress. This year, I learned a name for this artform: hapa zome. There are many ways to do this, but what worked for us was to put a block of wood on the table, put fabric on top, then place leaves and flowers on it, followed by paper towel. Then hammer! And hammer! And get all the juices you can out of the plant.
So much fun for any age. As long as you can wield a hammer, you can enjoy this craft. I'm thinking that some year, I'll make a quilt with blocks of flower-printed loveliness. Some year.
