Making your own bag
For me duct-tape is what to use when rig the PA. There's a wonderful story about when a singer in a band was sent to the store to get duct-tape. But since he is very 'economic-minded' (or you could call him stingy) he was returning to the set with rolls of tape to be used in the freezer...
This Duct tape bag was a real home-work. It feels a lot 80's. But the site is good since you can make your own duct-tape bag - there's a walk-through and all.
