The question I actually meant to put out there - just before my mind side-tracked me - is this:
how does everybody deal with moths? Do they even exist where you are? Do you use artificial moth repellents? Sandal wood? Lavender?
I have my own fabric to think of and then my husband dropped the last two metres - ever! - of vintage upholstery fabric for his vintage (dare I say it?) Porsche in my lap. It's a gorgeous tweed and needs to be stashed away for future car seat maintenance. It must not under any circumstances become moth fodder!
