Blast From the Past: I haven’t put up this year’s Christmas tree yet. But I was just reminded of this photo I took exactly three years ago today. That year, in addition to my more typical Christmas tree, I did something I’d been wanting to do for years: I built a Christmas tree (and friendly snowman) out of books! Creating it was more time-consuming than I had expected, but all that work did result in the coolest Christmas tree ever. Why stop with books as presents under the tree, when you can have an entire tree made of books?
