I am installing these glass panels on my stairs. Although I have a solution to install them in such a way that the top edges will line up, the glass panels will not sit properly centered on the treads.
I just realized that one way to fix this is to shorten one of them by cutting the bottom edge and after that polishing it a little to look almost perfect.
These are 10mm thick glass panels I have a wet saw and I also have a Professional Carbide Tungsten Alloy Handle Glass Cutter Tool with Range 2-19mm Professional Cutter for Thick Glass Mosaic and Tiles - Pencil Shape & Design (Glass Cutter) (Regular)
