I do have the wicks pretty tight. I found this happing to sometimes w/a square braid 1/0. Yesterday whille waiting for an answer, I tired to wax a few wicks. Well let me tell you...by the time i got them all set up in the mold, they were flopping in the winds...did 5 and decided to go back to the old way. I do have a bunch of CDs that I mainly use for containers. I have some larger ones and see what they do. Thank you for the feedback. Wendy
