I have been working on some small wallet pieces, dyeing in two different colours (Fiebings USMC black and oxblood for different wallets) however, I have seen an inconsistency where the oxblood dye completely obsorbed, looks incredible and doesn't come off on my rag what so ever when I buff it. However, the black seemed to dry on top of the leather and comes off to a great extent onto my rag and I can see some of the original leather colour through the dye. I am going to attempt a second coat tomorrow morning to see if I can get the black to hold a consistent colouring, However I just wanted to ask and ensure this is a normal occurance.
P.S. I simply dampened the leather and then applied the dye with a sponge. I have heard about watering down the dye but was just keeping it simple for this test.
