I don't know where I came up with the idea of putting a ladybug on a mushroom bead. I think I saw some other toadstool beads witih leaves and catepillers on them and then thought: "hey a ladybug would look cute." I had just made a ladybug on a leaf bead. Perhaps I saw a drawing or illustration, now that I look for this combination, I have seen several other items that are similar.
I however did not see this really beautiful photo. I was using Stumble to look around the web and found this beautiful photo by Edwin Kats. Look there is even a bit of greenery. Art imitating life!
