Hi Anismary,
ok,I use the smaller newspapers,like the "Sun" etc.I use two sheets together for the thickness to make the pots last longer.Roll the newspaper on to the rolling pin from the narrowest edge of the paper(turn the paper thru 45deg form the reading position),when it is all rolled on to the pin,glue the edge with some craft glue.Do not roll your paper too tight though cos it will be difficult to get off the roller ;)
You should be able to get 3 pots from one rolling.
It is open to improvisation of course.Good luck,
Alan
