Another stitch I use a lot is the foundation half double crochet. It is very similar to the foundation double crochet stitch, with just a few differences. If you know how to make the Fdc, you can make the FHdc.
Foundation half double crochet (FHdc)
Ch 3, yarn over, insert hook in 3rd chain from hook, yarn over and pull up loop (3 loops on hook), yarn over and draw through 1 loop (1 chain made), yarn over and draw through all loops on hook—1 foundation half double crochet. *Yarn over, insert hook under the 2 loops of the “chain” stitch of last stitch and pull up loop, yarn over and draw through 1 loop, yarn over and draw through all loops on hook; repeat from * for length of foundation.
