What do you mean when you say double over when tying in the krystal flash? Also as I understand and as I saw in the slide show video, you lay the chenille on the hook with one end at the head, tie this in going back to the length you want the body to be, then tie back to the head. Then wrap toward the head and finish. As I see this you end up with the chenille being tied to the hook starting at the head tying back to the length of the body returning the thread to the head before wrapping. You will be wrapping over a full body length of chennile tied under to the hook. Or do you just barely tie in the end of the chenille back away from the head, tie thread up to jig head, then wrap. With this method you would only be wrapping the chenille over a small part of the chenille that you tied in and not a full body length of chenille. Thanks
