Pattern: Royal Moonshroud Bracers

nope. if it would do that then there would be no point in having 2 different recipes.

I was on my non-tailoring character and saw Pattern: Royal Moonshroud Bracers (Horde) on the AH for a deal. I checked Wowhead and it did not show that I had it learned on my tailoring (Horde) character. (I can see whether I have collected a recipe or transmog on each of my characters, on Wowhead, by "pinning" the characters on Wowhead; it shows a green circle with a checkmark for each pinned character that has completed it.)

I almost snatched it off the AH, but decided to log into my tailoring character to double-check. And sure enough, I had learned it already. Learned items don't show right away on Wowhead, but I'm pretty sure I must have learned this one quite awhile ago because I don't have a recent recollection of buying or looting it. I think maybe Wowhead didn't correctly show this one as being learned because of something to do with the separate versions for Horde and Alliance.

So if you're somewhat of a completionist like me and can't remember all the patterns you know, check on your tailoring character whether you already know this, rather than relying on Wowhead.
