So, I thought of this idea for the contest and made it (with Kate's help rolling rosettes and picking leaves off tall trees - thanks for that!) and wrote the post all in one day - phew! The theme was "natural".

First, collect the leaves - they need to be pliable (err, "bendy") so I pulled them right off the tree. Then cut a circle wreath form out of a discarded box - I had purchased wreath forms that were twisty, but they weren't going to work - the cardboard was perfect.
To attach the rosettes to the wreath form, just use a generous amount of hot glue. I did not cover my wreath form first, but I wish I would have - so I'd recommend gluing down a layer of flat leaves to start, that way there's no risk in seeing cardboard. For my edges I wrapped leaves around and glued them like so, to hide the cardboard:
