I have placed two Wise Leaf ornaments and one Cheerful Acorn outside my mom's house to see how they stand up to the weather. Two weeks ago my friend got a leaf and asked if it was safe to put it on his covered porch... and I had to admit I didn't know! They are all sprayed with matte finish but I don't know how much protection that would offer. I'm also curious about how the waxed hemp cords will stand up to the elements.
Sooo, I hung the leaves from the plant hooks under our semi-covered porch and placed the acorn out in the open on a shrub. I feel kinda guilty sacrificing a happy little acorn fellow, particularly since it's pouring and freezing out today, but it's in The Name Of Science! (Hopefully I can fix him up again.) I'll see how they look in a week or two.
