Knit in the Round
You will need four double-pointed needles. 

1. Cast your stitches onto 1 needle only. Divide the stitches evenly among 3 needles by slipping them onto 2 more needles. 

2. Once all 3 needles have the same number of stitches, lay the needles flat on a table, loosely lined up end to end. (Your right-most needle should have the working yarn.) Make sure stitches aren't twisted; they should all face the same direction. 

3. Join the needles to form a triangle as follows: Take the left needle in your left hand and the right needle in your right hand. Bring the needles together to form a triangle with the middle needle. Pick up your fourth needle. With the triangle still in place (and the working yarn on the right needle), knit the stitches onto the left needle, pulling working yarn tightly to join (see figure A). You are now knitting in the round.

How to Increase
1. Insert left needle, from front to back (see figure C), below the horizontal strand between the 2 stitches. 

2. Knit picked-up stitch through the back of the loop, crossing your right-hand needle behind the left (see figure D).

How to Divide
Slip first stitch purlwise onto a double-pointed needle. Slip second stitch purlwise onto other working needle. Repeat, alternating (see figure E), until stitches are divided equally between needles.

How to Decrease (knit 2 together)
Slip needle knitwise through 2 loops, not 1 (see figure B); knit both stitches together.
