All-in-One is a product sold by Tandy Leather. It is both a dye and a finish all in one!
It works very well in situations where you want to dye a complete piece of leather. It also has a darkening effect in tool impressions. The finish is much like Super Sheen, a water based acrylic finish. There is therefore no fumes to sniff or worry about.
In this little video, you will see how this product is applied and how the excess is wiped off. Take care to wipe off lightly enough so that the All-in-One is left in the tool impressions, and do not get wiped out of those depressions - you want it to dry there to have the eventual darker effect.
The photo below show the finished piece of leather incorporated into a card holder.
(The back part of the card holder was done in the frog skin pattern shown else where in this blog and then it was colored with acrylic paint.)
