I had a rolling machine at one point too, you know those little red ones?! Romford market has a stall that sells nowt but smokability paraphanalia!
The thing with them was, sometimes they would play the fool and you'd roll it and the bloody thing would pop open! Baccy etc in lap!
yeah used to hate it! my aim of life at one stage became to roll the perfect blunt! hahaha how mad was that!
