More than willing. Not doing trade secrets here, I encourage everyone to get out and try to do it themselves. I have the Sihouette 'Cameo' model running "Designer Edition V3" software. I set it on "paper" so I can control the blade settings. The material I use works best with speed-3 and thickness-5. Blade depth is 2.
This is the material I use for masking. I buy it in the 24" X 10yd size and then chop it into 12"X12" sheets for most of my work. You do not need a backing sheet and can feed it directly into the cutter. I have done 12" X 55" pieces for the side art on this pinball. Worked out quite well. (It's a few pages back.)
I use this to ease the transfer of the cut stencils. You cut and weed, lay the app tape over top of the vinyl and then position it. Once you have it in place, peel the back and lay it, then peel off the app tape.
