I have been doing leather work for years, mostly all stitiching and making bags or cases or equestrian equipment just for fun. Recently i have been playing around with stamping and coloring leather. I am mostly making dog collars for practice. I recently had a request for different colored collars, red, green and blue. I bought some fiebing dye. When i put it on (with a dauber) i am having trouble getting the color uniform. i dye it and there is light spot so i go back over the light spot and then the area around the edges gets darker. I dyed one green color and by the time i finished it looked black because i had kept filling in the light spots. If anyone can give me some technique advice i would really appreciate it! thanks.
