Saral (blue) standard box. https://www.turners-retreat.co.uk ....£9.75 per roll CHEAP!! stock up, buy 3
Stencils (HERE) $5 package & upward (as per recent stoney post) ;))
Iceland the frozen food store, £3.00 is actually buying good size pumpkins for the uk this year, buyers have asked for bigger pumpkins from growers (peculiar but positive) ...as I "thunk" it means you could pillage a crate at a local store & spending £30 means you'd be able to get em delivered

Stencil printing software? ...YES, stoney is correct I should have coughed up for the Ronyasoft license years ago, ..it works v. well. time saver!? ... you bet your boots!
