Instructables
Here's the thread on how to make the easiest multi stencil cap. This stencil cap is for a 3oz. can of spray paint. Its applications are for art and decoration. The paint technique is useful in many different ways, details, script, sparkles, doting the j & i, high lights, patterns, textures, touch ups, etc. How it's used is up to you. This instrument can be made completely on spec, if you have the tools to carve it out. Choose a plastic lid that isn't too brittle or thick.

Materials and tools
One or two extra caps
8 ounce spray can with cap (krylon shortcut)
Deco pen to mark on the dark plastic or sharpie to mark on light plastic
X-acto or Utility knife
Allan wrenches
Skinny tip Li hooded grey dot
Latex glove

The technique takes a little practice and some getting use to. Your first stencil caps will help you develop custom lines and dots. Once you've made few functional stencil shapes, redraw them onto another lid. The master cap should work only with the spray tip it's designed for, you may want to write the name of the tip onto the lid. In this case a grey dot will conserve paint, reduce mist and focus the spray hardness. Here are the two original caps, a forward angle double point and a star stamp. Since I know both these shapes work, they'll be transferred to the master cap. The stencil cut away area is always located a little below the atomizer (grey dot in this case) on the spray tip.

Thats a tight clip, at the end there's a calligraphic bit he does with the stencil lid. I'm getting the impression I should add a video too. The stencil cap is usually used with my index finger (I think thats what you meant) if that finger is hurting from excessive pressing I switch to my thumb. Including a finger slot is the proper way to make a stencil cap, with a multi cap this can present difficulties. The stencils are on the opposite sides of the cap to prevent the paint from misting out. If two finger slots are cut, the opposite side slot allows paint to mist or exit over the top of the lid. I'll make another cap that has the one large slot and two stencils two inches apart and try it.

Its good but you waste alot of paint doing that.

true, I forgot to mention that. The technique is not suitable for doing an entire painting, its only for very specific details.
Yeah, but none the less it is still a great idea and a cheap solution. :D

nice idea, i cant help but think that it would help to have the stencil further away, i kno that u can get some large lids that like clip on the inner bit of the can. otherwise well done
I like! Cool looking computer by the way.
