Colored Scud Back. I just got some good super strong material for many uses and it was not a dollar a yard. The wife was making Easter Baskets. The grass is great. At a dollar a bag I have enough in one bag to make a few million flies. I know many others have probably found this out already. I always tell my students to look at everything they see as potenial fly tying materials. I took my own advice on this one. John
