It looks like the wayward Technique: Origami Beetle finally made it into the game with the Patch 4.1 content. I've gotten two user reports (thanks fellas!) about this dropping in Uldum for Scribes. I'm also seeing similar comments from posters on Wowhead. The recipe appears to be a zone drop in Uldum. One of my readers got it from a croc near the Lost City, but from the Wowhead data it looks like it can drop from any mob.
The recipe binds to you, so you can't farm it on a different toon. Unfortunately I can't test out this information because my Scribe is only level 70. If you haven't managed to get a copy of this recipe yet, give Uldum a try!
