Chain 4, join with slip stitch to form a ring
Just a note - I like to only slip stitch in two stitches leading up to my chain 3 space whenever I start a new round and this is how the instructions are given here. One of my fellow crocheters also makes a slip stitch into the chain 3 space, and she tells me this is how many others do it as well. As you can see, my granny looks just fine the way I do it. Hers look just fine her way. You also should choose the way you prefer and what you think works best for you.Round 1: Chain 3 (counts as dc), work 2 more dc into ring *ch 3, work 3 dc into ring. Repeat from * twice, ch3, then join with a slip stitch into 3rd chain of the beginning chain 3.
