I am trying to make the edge of a diamond with chains in crochet with no stitches in the center of the diamond but I am unsure of the best way to get a 120 degree angle turn with only chains. I am needing what looks like a cookie cutter outline in the shape of a diamond. Is this even possible? If not, is there a stitch that I can use that will give me a clean looking obtuse angle with relatively few stitches? I need this exact shape with the space in the middle and everything.
