Adding the Millinery Wire Crochet over the wire just as if you were carrying the yarn along the round. Continue this until you get about 2 to 3 inches from the end. At this point, try to gauge how much wire you will need to finish off the hat. Cut the wire and unravel a small portion of the rayon from the wire on each end, exposing the silver. Insert each end of the wire into the joiner. Use pliers to clamp the ends tight so the ends do not come out of the joiner. Finish crocheting the remainder of the hat as instructed.
