I'm usually strict advocate against gimmicks, but just occasionally I find one I like. This is a Potter's Pal I acquired from a company called Heaven in Earth. It would make a great project for a beginner woodturner as it is relatively simple, uses little wood, is functional but yet requires a number of techniques.
Simple to use. Fold / divide a piece of newspaper. Roll it using the column. Fold the base in and the mould it with the base piece. Once the seeds have sprouted into little seedlings transplant to the garden and allow the newspaper to finish breaking down in situ. I'm sure there'll be a little experimenting on durability and paper thickness.
But you don't need a gimmick to make paper pots check out this clip from Gardening Australia to see how.
