Embossing Suspenders
Hi everyone,
A friend of mine is getting married, and he has decided to gift a pair of trouser suspenders (or braces, for my friends in the UK) to each of his groomsmen. The're made mainly of fabric, but have a small leather patch. (Picture attached.)
He has already purchased them, and he has asked me if I could emboss a set of initials onto each of them. (To personalize them for each of his groomsmen.)
I have a stamping machine - from Dream Factory - that I often use, and which I've found to be reliable. Here's the problem: The surface that needs to be stamped is quite uneven. I thought about padding the uneven sections, so as to create a relatively flat and even surface, but it's quite risky and I don't want to destroy too many pairs with failed attempts.
Has anyone encountered this (or something similar)…

Solid advice. Thank you!
