Re: tube development

I use a piece of plastic screening inside a tube to avoid the scratching
and also allow the chemicals to cover both sides. I think I got this idea
from someone's posting on the list a couple of years ago. It has worked
pretty well. You can buy the screening at a hardware store and just cut it
to fit inside the tube.
