DIY gold leaf garland

I want to do this! I wonder how long it will take for mine to be a nice long garland to hang over the mirror above our fireplace. I also like the idea of the leaves as place cards. I did a version of my own a few years ago and painted actual fallen leaves gold for Thanksgiving dinner at my parents. They were a little bit hard to write on. This conveniently does not involve having to search the backyard for 14 perfect dry leaves with no holes or wilting. Instructions here.
