I'm hosting a "puffy hearts swap" in the Cloth Paper Studio Yahoo group. The swap is three for three, and I've made four - though I think I may have to make several more so they don't look quite this Valentine-y. I'm thinking of putting them on bases to make a heart forest...
In order to ship them flat, and let the recipients stuff them and use them as they wish, one side has a small opening - thus the strings hanging out to enable the recipient to close them.
