Until recently in Oz, bread tags (i.e. little square bits of plastic with a hole set in from the side uand used to keep the plastic bread bag closed - hard to describe) were the common alternative to plectrums if the nasty little critters decided to go walkabout in the middle of a session.This explains why guitarists are often heard complaining that they don't have any "bread" (sorry - NOT *BG*)
Unfortunately for guitarists, but fortunately for the fish, someone invented a more environmentally friendly alternative to bread tags. (Apparently if the tags make their way via littering into the waterways the fish choke on them. They are also dangerous for little kids & babies.)
