No. You actually baste a piece of the canvas on the garment & stitch your crosses like you were using plastic canvas. It comes in different stitch counts, so you can make your design bigger or smaller. When finished, you use water on the stitching to either dissolve or soften the waste canvas. If it's the soften type, use tweezers to gently remove the waste threads.
Be sure to use a ballpoint or tapestry needle on knit.
