To cast on, insert your needle into the yarn about 2 in. (5 cm) from the end of the yarn. Pick up 2-3 threads of the yarn with your needle. This loop of threads on your needle counts as the first stitch.
Insert your needle into the yarn about 2 1/2 in. (6.5 cm) past the first stitch. Pick up 2-3 threads of the yarn, this is the second stitch.
Repeat once more so that you have 3 stitches (loops) on your needle.
Row 1: Hold the needle containing the stitches in your left hand. Knit across the row as follows:
1. Insert right hand needle into the first stitch on left hand needle and then into the yarn, picking up 2-3 threads of yarn as before to make a new loop on your right hand needle.
2. Pull this new loop back through the existing loop, dropping the existing loop from your left hand needle - one stitch knit.
3. Repeat to knit the remaining 2 stitches.
Repeat Row 1 to knit more rows, until almost all yarn in the first ball has been used.
Knot the end of the second ball of yarn to the first ball of yarn, then continue to repeat Row 1 until about 20 in. (51 cm) of yarn remains.
Bind off by knitting the first, then the second stitch; with the tip of the left hand needle, lift the first stitch over the second and off the needle.
Knit the third stitch, then lift the second stitch over the third. To finish, pull the yarn end through the last stitch.
Knot all yarn ends, then trim close to knot.
