Working through back loops of chains, insert hook in second chain from hook, yarn over, draw loop through leaving loop on hook, insert hook in back loop of next chain, pull up loop, continue in this manner across chains.
To work loops off hook, make a slip knot with the second color, place slip knot on hook, draw slip knot through first loop on hook, yarn over, draw through next 2 loops on hook, continue in this manner across.
For the next rows you will be picking up loops in the vertical bars of the previous row.
TIP! -- Here's a good rule of thumb to help you remember when to turn the hook. If you have loops on the hook, it's time to turn and change colors. If you have only one loop on the hook at the end of a row, do not turn; work next row with the same color you're working with.
