I purchased couple of cheapest picture frames from the local euro saver shop (couple of two packs for 1.49 each) plus cutting tool also for 1.49 , started cutting without any preparation/theory broke two of them, no luck! two days deep breathing...! Youtube ... "how to cut the glass" OK! feel ready now! let's start again, end of the tool to the oil (kitchen vegetable oil) make it wet and shiny .... and the pressure (pressure it the main point here if you push too strong on glass it will break but not the way you asking for) excellent! oil and the right pressure of my hand did the job just excellent ! Every time from now on! tried just for fun!
Experienced glass cutter :P
