You should find it easy to locate the BLACKJACKET™'s
sleeve cuffs with your hands without taking your head out of the darkened
environment. When you do, slide your hands into the sleeves of the
focusing cloth--from the outside.
You'll discover that the loose
folds in the fabric preserve
the darkened environment whether your arms are in the sleeves or
not. No more annoying light leaks to make focusing difficult! To see
how well it works, proceed to the next frame for an inside view.
