Started tying some hair jigs this week. I'm using 1/16 oz ball head jig with no collar. As Im tying it seems like my collar keeps getting bigger and I end up with a collar about 1 third bigger than I want. Every wrap I make against the jig head seems to push the material back on the hook making the collar longer. I even glue the thread I wrap on the hook as a base before any hair is even tied On. Any help would be appreciated.
