Leather rolling after dying

[MICHAELALLEN]

In my latest project, I did some dip dying and all the pieces rolled. What did I do wrong? It made it very hard to assemble. Also from the difficulty I got glue on the panels. So I have two questions. One how do I dip dye and not have the pieces curl up on me and two, how can I clean this wallet of the glue without harming the finish? I was thinking about just using a conditioner to help remove it.

If you look in most leather stores they have erasers that will take off contact cement but just as easy roll it with your fingers. Your leather curling is from the alcohol in the dye evaporating. The fix is to bend and roll the leather the opposite of the way it's curled to straighten it out and oil before dying might help.

This is why I avoid dip dyeing.  I haven't found a way to prevent the pieces from becoming overly stiff, but a light coating of neatsfoot oil on the grain side will help.  Could also experiment with oiling or casing the leather before dip dyeing.  I use Fiebings deglazer to clean up Barge cement on bridle leather.  It dulls the finish a bit but that is fixed with a conditioning balm like Aussie or Leder Balsam.
