Observe how the edge is "prepared" in the original screen.  Usually there is
a reinforced cloth "tape" sewn or glued to the material for strength, so
that the grommets do not pull out when the material is stretched.

A frame can be made out of nearly any material, but keep in mind strength,
stiffness, and weight.  Theater screens are often supported in frames made
from 2 x 4's, and even 4 x 4's and 4 x 6's, and these are usually bolted to
the frame of the building.  Frames for smaller commercial/industrial screens
are often made from extruded aluminum "square tubing", and hinged to fold
down for shipping.  These are often very expensive.

Frames have been made from lead plumbing pipe, but these are obviously very
heavy, not good unless it is to be a permanent installation.

I recently made a frame out of PVC plastic plumbing pipe (the beige stuff,
not the black stuff).  This material is relatively cheap, and is easy to cut
(an ordinary hacksaw) and glue (PVC dissolving type glue).

It has the drawback that long pieces bend easily, especially if you are
trying to stretch a screen to it.  However, since it is lightweight and
cheap, you can brace it with several cross-pieces behind the screen.

Once your screen is mounted and upright, be sure to apply masking around the
sides, completely covering the frame so that the pipe cannot be seen by the
audience.  Black photographer's velvet works very nicely for this.
