Stapling seems to get a bad rap. Using 1/4" staples, applying the Spandex becomes a very simple, easy process, and any needed removal is effected with the tip of a Butter Knife.
Using Screen Spline is of course a method that allows a quicker dis-assembly, but in the same regard it requires that the stretch be made / held over a longer area before the spline is inserted, so I'm not seeing where in fact it's use makes the Job any easier during initial assembly. Screen Spline makes pretty good sense when a actual Screen material, or Blackout Cloth is used, because those materials do not stretch much, if at all, and they can be prone to ripping / tearing. Not so Spandex. In the time I have been using it, and have had to remove a few Staples, even inserting a sharp point under the stapled Spandex did not result in any tearing or perforation. Spandex is pretty resilient to tearing, being so "stretchy" and all.
But the question pertained to Trim, did it not?
If the perimeter of the Spandex Screen is greater than the actual viewable area, then one should Wrap the baseboard with velvet first, then simply apply the Trim to the Screen Frame using small, 1.25" Bright Finish Nails if one does not have a Air / Battery Powered Stapler that uses the even shorter, smaller 1" Finish nails.
Applying Velco to a stretchable Cloth, and then expecting it to hold lengths of Trim firmly to / against such a surface (especially at the Mitered corners) seems pretty misdirected. What happens when you determine to pull the Trim back off? Unless you also staple the Velcro base pad to the Frame, it will pull outward with the Trim, and possibly ruin your Screen's stretched surface.
