Bought some thin lucite acrylic 2ft x 4ft panels in the crackle ice pattern and am having problems with cutting it. Was told at the time of purchase to use tin snips but that is not working. Also tried scoring it but that does not work too well either. Am using it as a cover and light diffuser for fluorescent lighting above our kitchen cupboards. All cuts are to be straight ones but would like it to be somewhat even and not so chipped looking. What is the best way to cut this stuff. Thanks, Mary Ross.
