Puff St – half double crochet puff stitch – basically this is a hdc3tog all in the same stitch – Yarn over the hook, insert your hook into the specified stitch, yarn over and pull up 1 loop (3 loops on the hook). Yarn over the hook, insert your hook into the same stitch, yarn over and pull up 1 loop (5 loops on the hook). Yarn over the hook, insert your hook into the same stitch, yarn over and pull up 1 loop (7 loops on the hook). Yarn over the hook and pull through all 7 loops. Stitch complete.
I used the hdc3tog in the Pretty Pebbles Stitch Tutorial. In this tutorial it was called a Cluster Stitch (often Puff and Cluster are used interchangeably). You can see how the stitch is done by looking at the tutorial photos included in the Pretty Pebbles Stitch Tutorial. View images 3 to 19. Do not follow the exact instructions as the Pretty Pebbles Stitch project does not follow the same full pattern as this scarf.
Simply Scrumptious Slouch Hat

at this point the band should measure 18 inches long by 3 inches wide
You will be working along the ends of the 36 rows of the band.
Step 1: Work 39 sc evenly across the edge of the band. Bring the two ends of the band together and continue working around the band in continuous rounds. You do not need to slip stitch to join.
Note: You can either whip stitch the edges of the band together now or wait until you are finished the hat.
