You can get something close. the old acetate finishes (stratas) were actually the colored acetate melted together, put in a large square block, stirred to mix and create the lines, then let harden. After cooled, they would shave thin sheets off of the block. They also cut out small blocks for eye glass frames.
Currently, no one is making or offering a true strata finish. I have been on the hunt for some Ruby Strata, even going as far as getting a quote from Delmar. At $59 a sheet with a 400 sheet minimum, it was a bit out of my price range.
A place called Drum Foundry is working on creating something close. You can see them here:
