Do you tie flies on a 4/0 hook? If so, please post a picture in your reply to this message. Somehow I ended up with 400 size 4/0 Sealy hooks. I have no idea what I'd tie on hooks this big so I'm just going to give them away. The boxes say 1764.B on them. If you tie flies on hooks like this, you can have them for the cost of shipping ($3?) if you send me two of the flies.
