For smaller projects, you can get the tri-folds made of heavy cardboard (kids use them for science project displays at science fairs) and glue felt to the inside surfaces. They can be purchased at Wal-Mart or Hobby Lobby for around $5. Fully opened, they allow for a decent working area then fold up to be easily stored away. A project could be left folded up in it as well for protection until the next time you are ready to work on it.
