To make a magic ring for crochet projects, first take the yarn and form a loop, leaving a long tail. Using the hook, pull yarn through the loop. Chain stitch one, then single stitch in the round the number of stitches needed. Pull the tail end to close the circle.
A magic ring is a beginning stitch in many round crochet projects. It appears in patterns for hats, toys and accessories. The same technique can produce a double ring, using two loops in the first step. Double rings are very helpful when using lightweight yarns or for projects that may get a lot of wear.
