How to: Foundation Single Crochet

Foundation Single Crochet (Fsc): Ch 2, insert hook into the 2nd ch from hook, yarn over, pull up a loop (2 loops on hook), yarn over, pull through 1 loop on hook (this makes the ch), yarn over, pull through 2 loops on hook (completes the sc).
Next Fsc: Insert hook under the 2 loops of the ch of the last st and pull up a loop, yarn over, pull through 1 loop, yarn over pull through 2 loops.

The foundation single crochet is very helpful if you find your chains are too tight at the beginning of a project. It also eliminates having to chain and then sc in the chains because it creates the chain AND the first row of single crochets at the same time.
