We've been using paper pots for over 30 years. Used to roll quartered newsprint around Henry Reinhart ale bottles because they were smooth. These days I've got a fancy olive oil bottle that's taller. Simply roll the paper evenly around the bottle and fold the bottom down in pie sections securing the loose end. Slide the paper off about 1/8" and roll it on a hard surface to crimp the bottom. Slide the pot off of the bottle and fold a half inch of the top creased inside. No fancy pot maker. Now, we do NOT plant the whole pot. I imagine it would digest under the soil eventually but we've never had any real issue with transplant shock and the used paper goes into the compost.
