I was buying Thavnarian Silk from MB and I saw someone put wrong price. It's only 11,8k per pieces. I instead buy 2 pieces and trying to make Thavnarian Armlets (and trying to HQ). But I failed on 2 times Rapid Synthesis and then the synthesis is... failed... NOOO MY CHEAP SILK!!

...

Moral of the story: Just sell the silk again for safety reason (Or make NQ one than HQ)
