For those who don't know the Chainless Foundation Method, here is a step-by-step photo tutorial to help you learn:
Insert your hook into the first chain and pull up a loop.
The next step is to pull up another loop through the loop you just made.
You'll then pull up a loop through 2 loops on your hook. You have now completed one single crochet.
To work the next CFM, start with the first yarn over and follow the steps again. To work the next stitch, insert your hook into the first chain you created in the previous stitch and pull up a loop. Continue from * to finish the stitch. Repeat this step until you have your desired length.
This is what your first row should look like. You have worked the starting chain and first row of single crochet all in one.
