Searching for Inspiration - My Next Mantle

I already know the theme I want to use for my next mantle change, so I went looking for inspiration for decor.  I am especially looking for ideas of things that I can make myself.  Do you think you can figure out what my theme might be?

I visited two of my favorite stores for inspiration, Hobby Lobby and Gordmans.  Where do you go to find inspiration in decorating?
