I always carry a small leather pouch that I put seeds or small stones, feathers and anything else that may strike my fancy that I come across on my walks through fields, lanes and in the forest.
Needless to say, I have collected quite a few items that I NEEDED to bring home. I find this relaxing, and sometimes I get a surprise by the stone being semi precious, or a seed grows some sort of very unique flower or plant.
I have a special place in my house of the gifts Nature has given me. It makes one remember just how small we really are in this Universe.
