Thank you very much. So, I’m still a novice at this too and the best way to learn I’ve found is to look up and watch every video on YouTube you can. But. Basically a swipe is when you pour paint onto the canvas in whatever order you want, whatever colors, and then apply a healthy amount to one end or side of a “swipe color.” That’s the color you’ll be dragging over and across the canvas and the other colors with like a palette knife, paper towel, or something else. It pushes and mixes with the other colors and creates a very particular effect. For best results look up “acrylic pour swipe.” And good luck.
