Chain
Chain 10 or more stitches with your yarn and crochet hook to make a foundation. Leave the last loop on the hook.
Yarn
over
Pull the long end of the yarn behind and over the top of the hook to yarn over.
Hook
into third stitch
Count to the third chain from the hook and insert the hook through that stitch from the front to the back.
Yarn
over and pull through
Yarn over and pull the hook and yarn back through the stitch.
You should now see three loops on the hook.
Yarn
over and pull through
Yarn over again, but this time pull the yarn through all three loops on the hook. One half double crochet stitch is finished.
You should now have one loop on the hook.
Repeat
to end of row
Yarn over and insert your hook into the next chain. Repeat the procedure and continue to the end of the row.
Chain
to turn
Chain two at the end of the row, and then turn the chain around to the other side.
Read your pattern carefully to determine if
the chain two at the end of the row counts as a stitch. If the
pattern doesn’t specify, then count it.
Work
next row
Yarn over and work the first half double crochet of the next row, and each row after, into the second stitch from the hook.
