When you slipped stitched in 12th ch from hook you made a ring... in that is where you do the 6dc. and than skip the next 3sts on your previous round you were working on ,,,,not the hook of 12ch,,,, do a sc in next st of that previous round and than go back to the 12st ring and do 8 more dc ... I hope this helps you... just try to do what they are saying step by step and see if it looks right to you... I wish I could show pictures for you step by step but am not able to.....I hope this helped mainly you are working on the reg . row and doing dc in the 12ch loop you have made......good luck and Happy Crocheting Davena
