Hello all.
First day here and I have questions already

I'm in the beginning stages of starting a Dark Sun campaign that's been brought up to date with 3.5ed rules. Well, for those unfamiliar with the setting, it's a desert world. And from there it just get's plain weird. All that aside though, I thought--wouldn't it be cool to have map backgrounds that looked like reptillian hide/vellum. Large croc/dino sized scales, tiny to medium serpent style scales, vibrant colors that look faded or bleached by the curing/tanning process. Aging that differs from what would happen to parchment. Maybe even some organic, primitive pallets for the inks used.

Has anyone ever seen anything similar to this or suggestions on how to accomplish it?

Any input would be appreciated.
