I am originally from northern Minnesota but now winter in the south. I am up in Minnesota late this year. I bought myself a wool blanket shirt that I wear under an anorak when I am out birding. It is very thick, very warm, very pricey (so I want to preserve it) and not moth proof. I will be leaving in a few days. I figured the winter cyclists here might know how I should store this so it doesn't get moth eaten. Suggestions? Moth balls are not appealing.
