"Here is the number to the Co. I get them from Precision Lure's Inc
(870)528-4016. They sell in quanity - thousand at a time. If you dont need that many we have a member that makes them. try his site
www.getbitlures.com . If you do use Precision tell them Ted from HappyTime Hand Pours sent you. As far as attaching them I tried lots of ways from hot knife irons - candle flames - and the best way I think is a portable blow torch you get at home depot for like $19. get the one that shoots the flame at a 90 degree angle. Fire it up on a low flame hold skirt in left hand and bait in right, touch each one to the flame at the same time for just a second then stick together. its that easy. I do wear a respirator and make sure you have air flow. the torch can suck all the oxygen out of a room. I do it in my garage with my door open."
I searched and found this info....you might want to to a search for tube skirt there was quite a bit of info.
