For a wreath you can use year after year, try durable felt. Pick up some felt puffs from your local craft store and glue or pin them onto a foam wreath form. White puffs, like the ones used here, make for a great "Snowball Wreath."
You can also try cutting festive shapes out of felt sheets, and attaching those to your form.Shown:
