You can get glass etching stencils for your project through a variety of different processes.
There are many different thicknesses of vinyl to use for your glass etching stencil and the thickness depends on the etching method your doing. The thickness is measured in mils and the higher the number, the thicker.
When using etching cream, the thickness doesn't really matter and a cheap piece of vinyl will usually work great for any project. Most people use Contact Paper which can be found at nearby "office" or "craft" stores. It works great because it has a adhesive backing to it so you can stick it to your glass and prevent the cream from etching areas without intent.
If you plan on sandblasting glass, you will usually need to get a thicker vinyl material and it also depends further on the depth of the blasting into the glass. For light surface sandblasting or when using the abrasive shading technique, a thin piece of vinyl such as Contact Paper may be adequate. Contact Paper is about 2- 3 mils thick and you can always double or triple the layers up if you wanted to.
When you're etching deep into the glass, known as Sandcarving glass, you will need a thicker mil to withstand the high blasting pressure. A suggested mil should usually be anywhere between 5- 25 mils thick. It is always a good idea to find a vinyl that has a adhesive backing, so you don't have to apply glue yourself. This saves a lot of hassle when placing your stencil resist on your glass piece.

Here we traced the stencil pattern onto the vinyl resist and hand cut it with a exacto-knife.
Below is a automatically cut glass etching stencil from a computer driven equipment. These can be expensive, but our info. manual saves you hundreds of dollars. Consult the manual of where to get these cheap and how easy they are to use after getting it set up.
