A Cricut Maker is a wonderful little machine that can cut cloth, paper, vinyl, thin wood, cardboard, etc., up to 12x24 inches. I have used mine to make pot holders, greeting cards, fabric and paper flowers, and all kinds of cool stuff. For a mask, all I need to do is program the machine to cut the pieces and sew them together. I love the Cricut!
