Here are a couple more how to's http://www.ehow.com/how_7941_make-tile-mosaics.html http://www.monstermosaics.com/how/index.html TLC- If you have a toolbox with basic tools your in luck. To cut a straight line all you'll need is a flat screwdiver, a straight edge (a ruler works great), and 2 pairs of pliers, preferably not needlenose. Lay your straight edge along the line to be cut, take the edge of the screwdriver and run it along the straight edge to score a line, you'll need a little pressure to get a good score, run it back and forth a couple of times if needed, just make sure you stay on the line...the score doesn't have to be very deep. Now take your pliers, one on each side of the line (it doesn't have to be all that close to the line) and "snap" it like a Hershey Bar. To protect your tile you can wrap the teeth of the pliers with some tape or cloth. This works for ceramic & porcelain, maybe even glass, i've not tried it with glass, I use a cutting wheel for that. Please forgive me if this sounds confusing, but after a few times you'll get the hang of it.
