12:1 "feather" simply means to grind it back on a taper - like scarfing two pieces of wood together. The taper gives a stronger bonding surface. The first layer of glass should cover right out to the edge of the taper and subsequent layers each get smaller until you have the required thickness. Sort of like a topographical map if you will. The number of layers depends on how many it takes to bring the surface up to where it needs to be. That varies depending on how thick the original glass is, the weight of fabric you are using for the repair and so forth.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
