Well I was told it's an old Irish Blessing. I'm not convinced, but I thought it was cute. I don't have any stamps or digi images of frogs in underpants though, so just did a plain frog on the front along with the blessing.
I added some faux stitching around the edge, a different type this time, with a green gel pen (to match the frog of course!) and white around the actual frog image to make him stand out a bit.
