To avoid sewing seams, you can work in rounds using circular needles or double-pointed needles.
To work in rounds, cast your stitches on one end of the needle the same as you would on a straight needle. Check to make sure that the cast-on lays flat and smooth and is not twisted. Add a stitch marker to the end of the needle to mark the beginning of the round (fig. 14a), and work the first round according to your pattern instructions.
Evenly distribute your cast-on over three or four needles, keeping one needle out to knit with. Make sure the cast-on lays flat and smooth and no stitches are twisted. If you'd like, add a stitch marker to the first needle to mark the beginning of the round. (It's easy for a stitch marker to fall off the double-pointed needle, however, so be careful.) The needles either form a triangle (if you cast on to three needles) (fig. 14b) or a square (if you cast on to four needles). With the empty needle, knit all stitches on the first needle. When that needle is empty, use it to knit the stitches on the next needle. Continue to knit the stitches from each double-point onto an empty needle, working the stitches as instructed in the pattern.
