Invest in an Exacto knife for durability and quality.
Use an exacto knife. CAREFULLY.
Exacto
Making your own stencils is a breeze if you have access to an exacto knife. Tracing an outline on paper or doing a freehand sketch and then cutting around it with an exacto knife is a great way to make your own stencils.
While four fingers firmly grab the knife, the thumb is placed slightly below the backside of the blade (on the "collar"), to increase the strength and accuracy of the cutting.
You need sheets of Vinyl an exacto knife and either stencils or a very steady hand.
You will need card board, pencil, scissors, exacto knife, glue, tape, a ruler and a good imagination.
Exacto knives can scratch glass, yes, but not with the first strike.
