This is an old revision of the document!
It's a lot easier than it looks.
hdc cluster: If it's starting a round ch 2, and if it's not starting a round begin an hdc then start a 2nd and third hdc with all loops on the hook; finally yarn-over and pull the thread through all 7 loops to make the cluster. The ch 1 that finishes it generally isn't included as part of the cluster.
Hook size: I; finished piece about 7.5“ with Rnd 6 or about 8.5” with Rnd 7.
ch 6, sl st attach (some like to use a “Magic Circle”)
Pattern is currently unfinished.
