Congrats on finishing your chair! Now you probably have a pile of leftover staves (and the two heads) and are wondering what to do with them. Here's a few ideas for those, as well as other things to do with wine barrels.
Serving tray: attractive, useful, and extremely easy to make.
Side table: very easy to build, can be used as indoor or outdoor furniture.
Ottoman: fairly easy to build, makes a good complement to the chair.
