We collected some autumn leaves a few days ago and melted some beeswax. (Our beeswax is red because I added some old bits of colored beeswax candles to our pot.)
We then dipped the leaves in the wax. All of the kids had a go at it. They were dry within minutes.
To assemble the wreath, I hot glued the leaves onto an old wooden wreath base that I had in my garage. It is lovely!
