A magic ring is a way to begin crocheting in the round by crocheting over an adjustable loop and then pulling the loop tight. The advantage of the magic ring method (below, right) is that, unlike the regular “chain 2, x single crochet in 2nd chain from hook” method (below, left), there is no hole left in the middle of your starting round.
Make a loop a few inches from the end of your yarn. Grasp the join of the loop (where the 2 strands of yarn overlap) between your left thumb and forefinger
Insert hook into the loop from front to back. Draw up a loop
Ch 1 (or as many as stated in your pattern). Note: this does NOT count as a stitch
Insert hook into the loop, so you are crocheting over the loop and the yarn tail. Draw up a loop to begin your first sc of Rnd 1
Complete the sc. Continue to crochet over the loop and the yarn tail until you have the required number of sc for your first round
Grab the yarn tail and pull to draw the centre of the ring tightly closed
Begin your second round by crocheting into the first stitch of the first round (below, left).
