Slip stitch/single crochet (ss/sc)
Holding the end of the chain firmly, insert the hook through the second
chain from the hook. Catch the wool with the hook and pull it through the
chain and loop on the hook. This leaves one loop on the hook and
completes the first slip stitch (ss).Work the next slip stitch into the next
chain in the same way. Continue working one slip stitch into each chain
until you get to the end. At the end of the row turn your work. Make one
chain and continue back along the row in the same way.
