Where did the info about 220 trivial come from? this isn't even up on EQtraders, and they usually have the most complete tradeskill info.
I am guessing the 199 skill for the enchanted, folded sheet came from there, though it should be noted that the trival on that combine is LESS THAN 199, as verified by my smith. Made the sheets with 199 skill, they were trivial, I'd imagine the trivial is much lower.
