These were super easy (and a bit messy for the littlest one), and the supplies needed were minimal. Because I didn't get this exact project idea from any one source, I'll give you the step by step.
1. Trace a shamrock on cardstock (important that the paper is thick - cardstock or posterboard) and have kids cut them out.
2. Take one napkin (I literally only used one, and there we many many leftovers) and cut it into tiny squares.
3. Have kids put a thin layer of glue on the shamrock about the size of one square, put down one square, and then have them put another thin layer of glue over the top. Repeat until as much of the shamrock is covered as you wish.
4. Once they were dry, I put them under a book for the night to help flatten them.
Here are our results!

Have fun, as always, feel free to copy!!
p.s. Just for grins, here is a shot of "day after" hair - remember the zig zag braids? Taken out, her hair got wavy!! We put it into two quick piggies, snapped on some bows, and were done in less than five - that's my kinda hair!!
