Oh my...DEFINATELY be aware of what poison ivy/oak leaves look like. When I was a child...many many moons ago...my sister and I collect " pretty red and orange, soft leaves" they were slightly fuzzy, so of course we rubbed them all over our faces. Yup, 2 days later, mother had us in the ER...Poison oak...IN the eyes, IN our noses, IN our mouth. Dont you know, we got our hides tanned but good...once we recovered. You could I suspect....strip the inside of a tree...behind the bark. Maple works really well...its thin and pliable. Of course....a good old rag works too. ( and maybe a rubber glove near the bucket!) :/
