Reply to "Lichen how to keep it from drying out"

I have some lichen that i picked out in the woods about 5 years ago, I boiled it in glycerin and rite dye for the colors I wanted, I don't remember the mixture but the lichen is just as soft and pliable today as it was when I first got it and I have done nothing to it since. There are many instructions on how to preserve lichen online. that was how I found it.
