Long Tail Tubular Cast On
First, we're going to get an odd number of stitches onto the needle in a pl, kl pattern beginning and ending with a purl stitch. This step is followed by two foundation rows where you knit the knits and slip the purls. I recommend using a needle two sizes smaller than the needle you plan to use for the main body to prevent flaring. To begin, measure 3 times the width of the piece you are planning to make.
