I hate dubbing. There I said it. Mostly because I am not very good at it and because I don't have the patience to learn it properly. I am wondering about yarn. I know in Al Campbell's articles he talks about using "punch " yarn. I asked a sales lady at a local Hobby Lobby and she didn't know what that was. When I google it I get websites about a punch yarn needle but from what I understand it is just a tool and can be used with all types of yarn. Which leaves me confused. Can someone clear up my confusion for me? My understanding is that polypropylene and wool yarn float. I am looking for a yarn to use in nymphs. Or should I just use them and weigh down my hooks?

Thanks in advance,
