I began collecting snowmen in 1996. I was visiting my mother in Michigan and we went on a daytrip to Shipshewana, Indiana, where there is a large Amish community. Amish equals quilts and crafts and fabric so I was in heaven! I bought the first guy - the one with the black hat on the far right in the photo below - and began adding to the collection gradually.
I received some as gifts. That tends to happen once people know you collect something. Maybe not so much if you collect gem stones or 19th century Impressionist paintings.
So now I have more than enough snowmen to fit on the mantel. A few years ago, I came across the bottle brush trees at a post-Christmas sale. They are an unusual darker green with gold sparkles. Some years, I display the snowmen in the dining room and decorate the mantel with more formal greenery, candles, and silver balls.
But the snowmen are such a happy sight; they always make me smile!
