This weekend I made a house sign using a piece of slate. I started by measuring the letter height I wanted and then went online to find some stencil templates. I then pulled each of the letter and number stencils into a Word document using the margins to help guide me with the dimensions I wanted. I spent about 5 minutes trimming the numbers out of the printed paper when it dawned on me: a piece of paper wouldn't hold up to spray paint. The paint would likely seep through the edges. Continue reading to learn about the rest of the project! So I reprinted the image on half a folder, which was a little sturdier. Had this project been thought out in advance I may try to find something impermeable like a piece of mylar. I also would have purchased a hobby knife to make the cutting easier. After taping the stencil to the slate using painters tape, I applied two thin coats of white spray paint and let it rest about 30 minutes. Finally, I removed the stencil before the paint was completely dry and hung our new addition by the back door.
