Ok, I have no idea where to go next. I just completed the crafting quests in DS and got my Master Artisan but he didn't tell me where to go next. I really want to get my Grandmaster Artisan - mainly because of all the blood, sweat and tears it took me to get this far. LOL Please if anyone can tell me where to go next, I will appreciate it so much!
Not to be rude, but, this question has been asked and answered many times in the forum here. A simple search would have told you to go see Pierce Stanson in the Floating Land of Celestia for the next Crafting Level.
You get your grandmaster artisan quest from a guy in floating land of celestia. When you come into floating land, he will be off to your left on the beach, by the water. He will ask you to make a necklace. A tip: start collecting all the stone block and black lotus you can !!
You have to go to Celestia to do this. It wouldn't let me on the floating land until I had finished quests and was given a quest to go there. When I went there the person I was sent to see also had the Grandmaster Craft Quest.
