DIY - Sharpie Coasters, ceramic tiles (free or very inexpensive at any home store center), rubbing alcohol added with a straw or eyedropper, (for the colors to mix) -- Great inexpensive gifts!(Diy Ideas For The Home)
I really like this idea for an office or a library. Convert an old globe into a pendant light! Seems easy enough. Buy a lamp kit at your local hardware store, take apart a globe and drill a larger hole for the light. Put remainder of light together.
