My Thermos collection is just starting out. I bought my first Thermos about six months ago - the plaid one below - at an antique shop. Recently I decided I'd like to expand my collection. Having a Thermos seems almost essential as a Canadian. They're great for combating the cold, whether it's a Thermos full of soup, hot chocolate, or coffee, it's something that will keep you warm. And since it seems like winter may never end, why not collect more?
P.S. Have you seen Elsie's (of A Beautiful Mess) Thermos collection? AMAZING.
