Use hard back books and magazines to make this look!
Where I have also seen unconventional Christmas trees is in CB2's Holiday 2010 magazine. I get them, you get them. What do you do to showcase those Christmas cards from your friends and family? One of CB2's 6-foot high mirrors which they put Christmas cards into a tree. One of my favorite ideas yet I have seen yet. Another idea that CB2 had was a ladder that they decked out as a Christmas tree. Cute idea for a warehouse or a community center or anywhere there are young youth.
In the Real Simple Magazine, they also have a book tree. Although it is smaller, it is great for a buffet or a sofa table where you can enjoy it weather you are sitting on the sofa or simplely walking pass the table.
