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.

Step 1: Cut Open the Top

First trace a circle on to the top of the cap. Use an opaque paint marker to layout where the cut out will be. The lid from an OZIUM air freshener will suffice as template for the opening. This hole shouldn't be two big otherwise the plastic looses its structure and cracks. The opening needs to be large enough for a finger to go in with out allowing paint mist to exit. Place the cap on your cutting mat and drag the blade around the circle while rotating the cap with the other hand.

Step 2: Transfer the Functional Shapes Onto Your Master Cap.

Use a straight edge and draw a line across the top of the lid, divide it into two equal halves. Continue to this line down the sides of the cap. This line lays out the center area were the shapes will be cut. Transfer the shapes by holding the caps together and marking the height of the shape onto the new cap. Remember to take note in your experiments if the shape was too high or low or not large enough. Now draw your shape right over the cross, repeat this process for the second stencil.

Step 3: Cut the Star Stamp 19/32 InchÃÂ From Top of Cap

Use the knife by dragging it across the plastic towards you. Watch out not to cut your self! First trace the shape with an X-acto and then pushed the utility knife through to make the cut.

Step 4: Cut the Forward Angle Double Point Line Stencil 18/32 Inch From Top of Cap

Take the knife push it in the plastic at the spot were you laid out a stencil template. Twirl the knife to ream a small hole, repeat for second aperture. Take a small Allen wrench to stretch the hole and make the circle even. Repeat this step for the second hole.

Step 5: Test It Out

Experiment with your new drawing instrument before you use it on your project. Always were a glove, roll your sleeve way back and watch out for drips. The cap fills up with excess paint, so empty it every 5-6 sprays. Blot the inside with toilet paper or a rag. Some people put an old sock over bottom of the can to prevent leaks. Be careful when removing the lid because paint will fly every where.
