What voodoo do I need to do in order to get this die to penetrate? I have tried three different veg tanned hides purchased years apart from each other (all from Tandy) with both the light and dark Fiebing's spirit based dye and have had the same experience with each of them. I have tried: cleaning with Oxalic Acid, cleaning with Denatured Alcohol, and sanding the top surface off. I have been using a swab applicator, but have tried dipping as well. Pictures are below. I have omitted many since they almost all ended up the same: Die on top of the grain with very little to no penetration. I have Al Stohlman's book on coloring leather, and have followed the directions as far as I know, so I'm at a dead end.
Everything but the two other combinations under it:
Below is the 3-4oz I dipped (dwell 30 sec), cleaned with Oxalic acid:
Below is one of the two 7-8oz hides I dipped. The other hide ended up much like the first.
I know there are several threads on this already, and that the general consensus is that the leather isn't really veg tan leather, or that it is veg tan, but with something else added. Since this is three strikes against Tandy, all spread out over several years, several locations in different regions, I would think that it would be better known that Tandy veg won't take die. Am I missing something? If not, is there anything I can do to make this leather take die, or am I stuck with prototyping and practice junk?
Your expertise is appreciated.
