We started a tradition the first year we were married to get a commemorative silver sleigh bell every Christmas. My mom gave them to us for a bunch of years and then she stopped getting the catalogue so we've been getting them ourselves for the past five years or so. The grand total this year is 23 (just counted on my fingers). This is the first year I've remembered to order this year's bell before Christmas though.
It was a bit of work but they are all so nice and bright and shiny!
