Eco-Flo for me has been a learning experience, but her is what I do/learned with this product. It is not fully tested and continue to learn, but I have yet to have any dye come off like others have reported here.
Carve/background ~ Allow to dry
After allowing it to dry, I will determine the dye color. If I am doing a belt, I will do the following.
In preparing the leather to dye, I will lightly wet the leather and dye it with Eco-Flo Dye and allow to dry over night. The next day or two if I have to corral the children, I will use an Eco-Flo antique as a final coat to fill up any empty or partially filled cells that were not covered in the initial dying process. I will allow it to dry another day or two. After buffing, I will use either Satin Sheen or RTC as a sealer and buff. Now, if the belt appears to be a little stiff, I will turn it over and rub in some neatsfoot oil and allow it to soak in and dry overnight. The next day, you should be able to feel the flexiability in the belt as you manipulate it. You can also rub down the grain down, if you are not going to line the belt.
Any other leather project or the use of another dye product, I will interject the following after carving the leather.
**If Tandy leather is used, I will use Neatfoot oil as my next step; it provides a slightly darker shade after application/drying.
**With my current leather (Hermann Oak), I will use EVOO (extra virgin olive oil); no significant change in color.
I hope I didn't confuse you.
