Here is what you do:
Using an I hook Chain an even number (I like either 30 or 32)
Row one: Single crochet in second chain from hook. Chain one. Skip a chain then single crochet in next chain. (So you are putting a single crochet in every other chain with a chain in between)
Row Two through the end: single crochet in each chain one space, chain one, and repeat until the end. (It is easy to miss the last stitch so look for the "V" made from the stitch on the previous row and make you sc after that. You will be making a sitch in your last chain of each row.)
Keep going until it is a square. Tie it off, weave in the ends, and go do some dishes!
Note: using a yarn that changes color is easier to see where you need to make your stitches. This pattern also makes a really cute baby blanket, just chain more at the beginning.
