I dug out some old hand-drawn illustrations I did ages ago and arranged them into little tattoos for Easter eggs.
If you'd like to make some eggs like this, download the free sheet of decals.
Print it on ink jet temporary tattoo paper and follow the application instructions on the package. It's super easy. After the decals are prepared, just place a trimmed shape on an egg (or yourself), hold a wet cloth on it for 10 seconds, and pull off the paper backing. Smooth out any wrinkles with your finger.
I used Silhouette brand tattoo paper purchased at my local PaperSource last year, but you can also get similar stuff from DecalPaper.com.
