Hello, do you maybe know, with what kind of procedure can you get the final color on this video ? I have already tried many different ways, but I can't figure it out, how to color the belt this way. Thank you for your response.

1. I made leather belt. I dyed it with FIEBING'S professional oil dye. After 24 hours I protected it with TAN-KOTE. Every step before next step I dried well. But: the dye leaves a trails on the trousers (dye stains on the fabric). Why? What I am doing wrong? What about alcohol based dye? What's the difference between FIEBING'S professional oil dye and FIEBING'S leather dye (= alcohol based) ? Does FIEBING'S leather dye also leaves a trails?
