Hey wonmorefish,
I'm trying to picture what is happening to you. Does the gold ribbing spin around the hook as you try to wrap over it?? I assume you've laid down a thread base and your thread and bobbin are hanging near the bend of the hook. Now take the ribbing (with a pretty long tag end - about half the hooklength) and pinch it against the hook with thumb and forefinger. While lightly holding it like that, pull the thread up between your thumb and the ribbing and wrap a couple times around the ribbing sliding under your thumb and forefinger each time - make sure you slide the thread back to keep the tie in point back toward the bend. Now take your left hand away and wrap a couple of mores. Remember your first couple of wraps don't have to be real tight. That is when the material wants to slide round the hook. Keep the first couple light to medium just to hold the material in place - then use a bit more tension - it doesn't take too much. You can trim the tag end or leave it against the hook shank and wrap the dubbing over it. This technigue works better with larger flies than smaller ones but experiment.
Hope this helps...
Jeff
