Watson ... both ways would work.
Though I think your mind and mine must be the same as I think yours would be the easier for stitching and precise results. Trimming after the black strips are added, using a template would create total precision!
Yes there would be wastage, but I can accept that when it is giving me precision.
To make the trimming job even easier, I'd get the local glass shop to make me a plexi template.
