If there is a rubber stamp store or a craft store with a large rubber stamping department, you might want to check and see if they have a die cutting machine. If they do, get colored self adhesive paper and die cut the leaves with the machine. If they don't have a machine, but have a Xyron, you might be able to buy die cut leaves, leaves used for coaster, etc. and run them through the Xyron to get a sticky back. If neither of these ideas will work for you, buy full page labels and print leaves on your inkjet printer and cut them out.
Many avid crafters own their own Xyrons, but the die cut machines are VERY expensive.
Run the papers through your printer for the names and such if you already have them. Go to a library, school or art store that carry ellison cutting machines to cut out the leaves. Or cut them out by hand but most libraries or public schools would let you use them. Before posting a message, please be sure you are in the appropriate category.
