I'll bet you created some beautiful fern chairs, Sandi.
I once bought a large new standing floor basket (rattan or wicker) from a popular Imports store, and when it was quiet in the house, I could hear something munching out in there. Never did discover the culprit(s) so either they lived out their lives in that basket or moved on.
Same with antique furniture. I have an antique cherry bedroom set with a couple of pieces that show signs of insect infestation. Not termites, probably wood borers of some type. Very common for very old furniture.
