Christmas Displays
I reused my American Girl library cards and books as ornaments for the mini tree on the desk in the Children's Room.
Rudolph the Red-nosed Bookshelf (cardboard antlers; the rest is construction paper)
My co-worker and I tried to just free-hand one of those trendy book trees and it flopped. About three times in a row. Here's what we learned: put a tripod on the table and stack books around it; works like a charm.
