Crochet a Puff-
This is normally a group of three or more half trebles,HTR, joined at both the top and the bottom. ( A three half treble puff is illustrated here.)
Step 1: * Wrap the yarn around the hook, insert the hook where required, draw the hook through a loop, repeat from * two ( or more) times in the same place. You now have seven loops, or more, on the hook. Wrap the yarn around the hook again and draw through all the loops on the hook.
Step 2: Often 1 CH is then worked to close the puff, as illustrated above.
