I use the mahogany and some of the other "darker" shades and I find that other than USMC Black they are all too dark so I cut them (normally 5:1) with Denatured Alcohol, they seem to cover more even and have a better color (thats 5 parts alcohol to 1 part dye). You can experiment and see what works for you. I find that if I don't cut them, they all get very close to USMC Black.

Thanks Ken. I will have to experiment with that and see what looks best. How do you apply it? airbrush? wool dauber?

Getting a good dye job is so dependent on so many things. Leather is a lot like wood in that different areas of the same hide has different absorption qualities. Then you add external problems such as oils, waxes, dirt and other things picked up off the bench, hands and tools.

I clean or deglace my leather before any dying. There are leather products for this, I use oxalic acid (wood workers bleach) to do the job. Keep a spray bottle of it mixed up and spray it on, rub it down with a good shop paper towel.

Leather is a material that is made up of fibers. Loose fibers will absorb differently than tighter so you need to open up the fibers to get an even dye penetration. I do this by handling my leather as I would to case the project for tooling. I give it a quick dunk in water or sponge on a liberal amount. I then let the leather set so that some of the water can be absorbed and swell the fibers. As in tooling when the leather has dried somewhat back to the natural color that I will dye.

Dye is a solid suspended or mixed in a liquid. With time as liquid will evaporate from the mixture you will get very small chunks of the dye. These chunks will not penetrate, and will just set on top. Make sure that your dye is well mixed be for you start. The most difficult way to apply dye is with a brush or dauber. As you touch the leather with a dye loaded dauber the dye is deposited in a large amount and absorbed, but as you move the dauber less and less is deposited. With painting on most surfaces the material is hard and you have time to move the excess paint around to even out the amount applied. With leather there is no extra to move around, basically more dye is absorbed into the leather as you touch the leather then when you finish. The only way to get an even dye job is to load the fibers up evenly with dye on the whole project. To get and even load on the fibers is with a airbrush that evens the flow of dye to the leather or dip dye. I like the dip dye to get better penetration deeper into the leather.

Dip dye, I place the leather into the dye long enough to see some small bubbles start to rise. This is a very short time and made sure that the whole project gets the same time in the dye. As I remove my item from the dye I shake off the excess dye into the bucket. I place the item onto my dye bench and immediately take paper, shop grade towels and remove the excess dye. As you place the item down you will see that areas have absorbed the dye into the leather. There will be areas that the dye has puddled, these are areas the the leather as absorbed what it wants in dye. If left the liquid will find someplace to go or will evaporate into the air. If left you will get a darker spot than the other areas, it will also be the areas that will have dye rub off after the item is finished. The rub off is because there was excess dye left that could not penetrate into the leather. With the paper shop towel I will rub and polish my leather, making sure all excess dye is removed.The biggest problem I had starting out with dyes was trying to be to perfect. As i finished applying the dye I would see light and dark spots so I would immediately start to try an even the color out. I would then get to much dye in one area and not enough somewhere else. I now dip and clean off the excess then leave it alone. You will see area that are darker but as the leather drys most of the color will even out. Sometimes I will have to do a touch up after a complete dry, but most of the time I let the leather dictate the final color. Good wood workers know that each piece of wood will have variances and uses these to produce a one of a kind piece.

Any way these are just my ideas and what has worked for me. I do know that I spent may hours practicing my tooling and other leather working skills. I would never actually practice my dying. After I ruined my fantastic projects, I finally practiced dying and figured out what worked for me.

I found that you can even out thge stain by using purell. I use it right after I stain. it has worked out well for me its a little cheaper than having to get every thing you need to air brush

That is interesting. I'm guessing the gel type? Does it dry out the leather much?

I used the gel type, and it doesn't dry it out. it seems to enrich the color also
