sorry veered off. roach is a whole chapter on its own. very important in english smoking culture.make sure to widen the roach hole as to see clearly the baccy at end of the empty tube. ive allways used clippers. n say 2cm by 3cm piece of card1 turn n a quart say slide in ,making sure plenty overhang, but not so much as to overtake length of roach n tuck it in . should have nice lil hollow tube. still think its prob too muchio green.
