So I thought I was giving my husband an easy idea for me for Christmas from my kids. Turns out neither of us could find a list of even one of these elements. I was surprised that Hallmark doesn't have it published anywhere but if they do, it's under lock and key. Anyway, since I have all the plushes, all the books, and am working on the ornaments, I figured I'd publish the list and help out others who may be looking for it like we were.
The plush dancing snowmen started in 2003 as did the ornaments. The books did not start until 2004 and while the illustrator remains the same, there are several different authors. Below is the comprehensive list (with pics) in order of year. The plush and book pics are mine so feel free to use them if you'd like. The ornament pics are NOT MINE. They are just screenshots of where I can purchase them so please do not use them.
If you can think of another way of organizing it or if I missed anything please, by all means, let me know. I want to make this as accurate and helpful as possible.
