yeah i have cut thin glass before. we will need a glass cutter which you can find for something like 4 bucks. we'll need to hack together a straight edge that extends all the way across to the other side. but other than that it isn't to hard... the biger thee glass the harder it is but 1/4 isn't impossible just more difficult than 1/8 which is what i've cut...
