I started tying a few years back, and love all the colors. Everyone here has to admit, if they're honest, that they have been disappointed in a creation that they had very high hopes for. After no interest they pick up the old standard and catch fish. Hence the question; why all the colors? Once I found a couple of patterns that produced I keep pretty busy tying variations of those. If it ain't broke, don't fix it? I enjoy tying the combinations and have been very surprised at a few that I tied from junk on the bench that caught fish like no tomorrow. That keeps my interest new and fresh, keeps me at the bench.
Creativity is just intelligence fooling around
