Set the end of the yarn against your non-dominant hand, on your middle and pointer fingers.Use your thumb to hold the yarn tail by your middle finger.
Wrap the working yarn down the back of your pointer and middle fingers.
Bring the yarn back around to the front of your fingers, crossing the working yarn over the first wrap to form an "X" shape.
Insert your crochet hook under the first wrap.
Use your hook to grab onto the second wrap.
Pull the second wrap under the first wrap.
The working yarn should now be on your hook as a loop.
Yarn over. (Wrap the working yarn around your crochet hook.)
Pull the working yarn through the loop on your hook to create a new loop (completing a chain stitch).
You should now have a somewhat secure circle with one loop on your hook.
Carefully remove the circle from around your fingers.
Your magic circle is complete!
Insert single crochet into your magic circle:
You can now begin inserting single crochet into the circle.Make sure you insert the stitches over both the loop and the tail.
Continue inserting single crochet into the circle, however many your pattern requires.The ring will still be quite open at this point, which is okay.
Simply pull the tail of the magic circle to bring the stitches together.
Continue pulling until the stitches tighten and form a circle, with little to no gap in the center.
You can then insert your pattern's next stitch.This will usually be a slip stitch into the first stitch or, if you're working in continuous rounds, a single crochet into the first stitch.
Your magic circle (with single crochet) is complete!
