Leather restoration help  

best suggestion
glassartist,
My best suggestion is to make contact with someone on a Rolls Royce forum. My brother-in-law did the leather on his car and it turned out very well.

A great suggestion
as the best I have found so far online was a BMW forum. We are on the same wavelength.

I saw a recent post
about damaged leather. Simon at the Danish Homestore suggested a tannery near him to replace the leather. Whilst I appreciate it's replacing, as opposed to restoring, it might be worth approaching a few tanneries?
This place looked useful too

i think i've mentioned it before here, but here's the link again. they created a custom colored filler and stain (matched to an armrest i sent in) for my eames 670 to fill in some cracks and touch up faded color. it's been 2 years and everything looks great, despite daily use.

I use leatherique on the leather in my classic cars. It works well.
