Problems With Dyes And Finishes

[Ligareaux]

Hi all, i'm starting in leather, i love many works from here and others sites, this is initially just for hobbie, but who knows !! ??

i bought some tools, dyes, edge kotes, etc

this is my very first try for a belt (thinking in christmas)

I missed some details in the edge near the buckle

my problems came with the dyes, when i applied they look good, but is too tight, when i fold for both sides, get some wrinkles and the leather dyed get cracks

how can i fix that? maybe with a deeper dying process? but dying i use fiebings products and applied with wool daubers

Cheers
