I loved doing this in art class. Art With Mr. E: Line Design w/Shading - Grade Very cool, fun art shading project from Art With Mr. E. he's an elementary art specialist. Try this with your kids (but I think grown ups would enjoy this too).
DIY simple and cute button bookmarks - What to do with all of those leftover buttons. Plus lots of other simple craft ideas. I know there must be something to be done with those cute buttons and my left over paper clips.
