In this tutorial, I use both Adobe Photoshop and Illustrator to convert traditional artwork into a vector to be used as a stencil.
You can use this to turn your linework, handwriting, ink paintings, and other high-contrast artwork into vector format. This is useful to make clean stencils, single-color stickers, single-color shirt designs, coloring book pages, etc. Afterward, it can be infinitely scaled to fit any size you wish!
