These patterns feature the Delta Crochet Lace technique. Similar to the square-based grid of filet crochet, delta crochet is a form of triangle-based lace which is defined by certain stitches and methods, including a vintage short-cut method of charting. The delta lace technique was particularly popular in Germany many years ago and is experiencing an international resurgence today. You’ll find both vintage and modern patterns among this collection compiled by the Delta Crochet Aficionados group on Ravelry.
