Thanks for the replies. I'm not sure if I should store woolens in airtight plastic bags, as I've read that plastic traps in moisture and keeps the sweater from breathing.

I live in an apartment and not sure mothballs would be a good idea.

But then I've read about storing them in a cedar chest. It's a tempting solution but I guess cedar chests are expensive. It seems that that's what people used before mothballs.

Am I OCD-ing too much over this anyway?

Thanks
Frankie
