Id like it more if the character would have a fame-pool that you could increase with those powder and perhaps other items that you could spend on a craftig task. Like you have currently 12234 fame and decide to put 345 into that tanktop that you'd like to craft. It should still be possible to find certain raw materials that got fame attached to it and it should also be possible to get fame by killing certain bosses and fulfilling certain tasks. That would make tailoring much more interesting.
