The steps are not that complex, but there is a few quick tips inside for when you just want a cool, repeatable stencil in 5 minutes. It may take you more than 5 minutes to read this, but once you got it down, you can really start cranking out stencils for all sorts of things! I have access to a nice silkscreen machine, but i still use this!
For quick overview the two main tips are:
- Drag your eraser through your outlined text (for quick "stencil-ification")
- Use two colors of spray paint for sharper edges
- Access to a laser cutter
- Vector Software (I use Illustrator, you can use lots of free open-source alternatives too!)
- Spray Paint (Two Colors! I'll explain later!)
- Paper or really thin cardboard (like cereal-box thin)
- Something to spray the stencil onto (A wall, a shirt, a millipede terrarium)
- Tape (I found this nice 3 inch masking tape at Ace Hardware)
Step 1: Create Image
So I have text and a full color image that I got from the internet.
Arrange them how you want in the graphics editor.
Step 2: "Stencil-ify" the Text
*Tip Erase a line through your text for stencil-ification:
First you need to turn your text into something that the eraser tool will work on. Choose "Type>Create Outlines," and all your text will turn into editable shapes.
Next, choose the eraser tool ("Shift+E"), set it on a small diameter, and drag it through your text. If you hold down the "Shift" key while you drag, it will constrain your erasing to a straight line. Just drag this line directly through the middle of your words to free the "islands" in the letters that would get lost!
Finally for your color image, click the "Image Trace" button in the upper left to get a quick silhouette. You may need to adjust the threshold to get the image to look how you want. If there are "islands" in this image that you want to liberate, you can use the eraser technique again. But for speed's sake, let's just go with it!
Step 3: Laser Cut
Make sure to position your design in the middle of your paper or cardboard, since you want nice thick margins around it.
Step 4: Tape and Spray
*Tip use TWO colors of paint:
the main problem with these types of stencils is that the edges can be ill-defined (fuzzy looking), if they are not all completely flush against the surface. Even with lots of work with different small weights and tape to hold the stencil flush, there will still be areas that might not be completely flush. I have found that using two different colors of paint (a black undercoat, and a blue overcoat), visually reduces the fuzziness along the edges since one coat may have been sharp in an area where another was fuzzy.
*Tip Spray from one angle:
Hold the can directly above the stencil and sweep your arm past in a lawnmower-like motion. Don't rotate your wrist or this different angle will spray up under the stencil in certain exposed areas.
For the big shirt stencil, I used cereal-box thick cardboard, and two slices (so it would fit in my laser cutter)
