Hers something I do, with my vises, don't know if you would think it a good idea, I don't really see all that great and not that bad either, but I learned from the folks on this site that the back ground in seeing a fly helps out alot, so I have a 9x12 inch piece of sky blue foam that I get in the craft section to lay on my table b-4 I set up my vice, it helps me alot when tying, makes seeing the fly alot eaiser...
