My coworker's got a sailboat, and she's planning to make some mosquito
net frames for the hatch. There are existing tracks that these will
slide down into, and the frames themselves will be trapezoidal.
A few questions: How does she secure the screens into the frames
(screen door grommet in routed grooves?); what type of screen
(fiberglass?); and short of teak, what's a readily-available wood that
will weather well?
