First things first, get you leafs and put them inside a book and let dry for 1 or more days.

Make sure its very flat (can work with a bit curly) to get best results.

My best advice is to try it with a little circle first. Thats why you should dry at least 2 leafs of the same kind to have a tester and one for the final results.

My Setttings worked on a leaf from a beech tree and made the fibers visible. 

Place on Baseplate and take some tape to held in place (touch the sticky side 3-5 times to make it less sticky and break you leaf)

1. Name signs for a Wedding with a more natural feeling
2. Highlight for a greeting card front
3. Door wreath with names of peoples from the home engraved or cut out

There might be more Ideas but I really think it's crazy to get these results from a leaf!

Have fun creating and I'm excited to hear from you what your Ideas would be! ~Anzy
