Are you using collar or no collar jig heads? With no collar tie in some chenile first then hold pinched at the top and tie 2 loose wraps and increase the pressure . To get them to flair be sure and tie in the thread at the same spot.They will spin like deer hair. With collar tie in a good amount of thread and glue this in first. Spin on the skirt material and whip finish. You can also tie in 2 small bunches at the top and then the bottom. You can also make some small skirts and slide them on. Some good video.
