Hi Folks: I have a 15x15 inch piece of ground glass which I want to cut down to 11x14. I'm used to a glass cutter but find that with this type of glass, I get uneven cuts when trying to cut off the small triangular piece in the corners.... I made a mess of an 8x10 sheet. Does anyone know if it's best to cut from the glossy or the etched side? -- Jim - http://www.hemenway.com
