Hi everyone, I see a lot of threads with people struggling to highlight their tooling with antique dyes, so I thought I'd share a technique I've been using that is easy and foolproof. I'm sure it's nothing new or anything, but maybe it can be of some help to someone.
Basically what I do is use neatsfoot oil the same way as a highlighter, applying it liberally and evenly over the entire piece. The key is to quickly wipe the excess oil off the surface with a cloth or paper towel, which will make the surface lighter than the highlighted areas when it dries. Pros: Fast, easy and foolproof Gives a clean, natural-looking highlight
No messy antiques or resists needed
Cons:
Doesn't give as much contrast as proper antique dyes
Too much oiling can lead to oversaturation, especially with thinner leather.
