Does anyone have any advice on the title subject? I would prefer to spend 0$ on tracks, as it seems easy enough to do with the right tools and some wood. I have acquired two 32"x20" sheets of 1/8" plexiglass, and I need to cover a 31 5/8"x38 1/4" space. I was thinking of just glueing three strips of wood in place on the the top and bottom, one inbetween the two panes, and one behind and infront of either one. Anyone else have any ideas?
