Here are the Christmas socks

I made these for myself and another pair for my friend, Ann. Brown Sheep worsted in Red Baron. Permanently moth-proofed with some kind of toxic pesticide. Do you think I've just done us both in??
Seriously, it is important to question these sorts of practices. Even if the FDA does approve it.... well, they approved Teflon, too, and after several decades of daily use, we're now told it's harmful to our health. So who should we trust.... our collective commonsense or the government? I'd like to know how many times I have to wash these socks before the pesticide is permanently removed! I'm also wondering if a skein of Brown Sheep in every stash might keep the dreadful moths away entirely.
