I'm the same - sewing machines baffle me. I'm going to try an experiment with using hand set rivets to support a large grid, that may be a possibility.
That sounds really neat. I think I would try heavy canvas or leather as a backer.
Thin plywood keeps the weight down, and gives it structural rigidity for the grid. But I do think there's lots of room for improvement and variation.
I agree but I can't take credit. I'm extending the ideas of others, just making my own modifications.
Weight isn't really an issue for me, most of mine go intro tool drawers. You would need a pretty strong metal frame to support the grid.
Lots of internet searching, plus a visit to the local fabric store.
