Hey everyone.  I've been trying to find some advice for this by searching but haven't come up with much.  I want to do some filigree Sheridan work, and have the colored panel behind be topgrain leather.  It seems as though to have a good quality piece, I'd have to have glue in every area of the veg tan, which must mean I have to trace the pattern into the backing pattern, to get glue in the right places if using contact cement.   Does anyone have any tips on how to do this well?
