I think that a pillow with a letter or a tray, bucket, etc... can make a conversation piece or even define a space. Have fun with this idea.
I have put a few pictures of some easy DIY projects that you can do to jazz up that chair or outdoor patio!
Take an inexpensive galvanized bucket (Wal-mart or Target) and paint designs and a monogram on it, then spray a sealer on it to make it water resistant. You will have to spray several coats to ensure that the paint will not chip off. If you do not like to paint free-hand...use a stencil!
