Vanessa Sellers in Dalaran sells these recipes for the shards. 4 shards for the "green" recipies, and 10 for the "blues". (thats tiny gold with the current prices of Dream Shards)
Here's a few screenies in case you were wondering what she sells:
Check your AH right now. There is little to no competition, alot of levelers out there needing them, and materials are insanely cheap. A 300g chant for 15g in mats? Yeah. That's the profit margin we look for, right? 2000% markup baby.
You remember a few months ago when these enchants were going for 1K and up? I do. Know why? BECAUSE THEY ARE BLUE (ok, ok, they were top enchants at the time as well). It's a common WoW mindset. If you are reading this, you know what I mean. We make alot of gold on items due to the fact that they are blue. The scrolls you will be making are that beautiful color, which in WoW is the color of money....
Before you get happy and leave to make your big bucks, don't. Go to Vanessa's partner in crime, Ildine Sorrowspear, and get a few stacks of Enchanting Vellum (she's got em for 10s, might as well pick up extra to toss on the AH "empty", as these sell for a few gold apiece as well).
Ok, since you are done reading this post, go to Dal, go to the AH, and make some cheese. Why? Because if you don't, the next reader will. =)
