Here's what I have in mind, subject to change as other parties actually
think this through for me:

1. it is going to take a bunch of these little magnets, but that is what I
want, their power times hundreds.

2. The magnets must be separate somehow. If they touch or clump, even after
being sewn in to individual pockets of cloth, that will not keep the cloth
from doubling over and over as the magnets find each other. Therefore,

3. I intend to glue the magnets down with hot glue, say, to a flexible
strip of plastic, some strapping tape, say, about an inch apart.

4. I will wrap the flexible but very strong magnetic strip in cloth and sew
it closed with a zipper foot, allowing enough left over to sew this strip
to the usual vinyl edging into which the screen is sewn. It is a plus that
the magnets are small enough to pass under a sewing foot if they have to.

5. I am contemplating different approaches to an entryway, I guess two
pieces with an overlap in the middle will do for a first pass.
