You have to correct the items that are necessary to make the armor types.

The quest will ask for a number of skin/fur volumes instead of the actual skin/fur itself. It made me buy 8 books of fur just to sell back 7.

Some of the armor items require boss soul gems, but this info is not listed or is hard to see. This is based on other peoples observations. Please update this as well.
    - Lvl 19 helmet - requires Long Da (Phantom City boss) soul
    - Lvl 22 girdle - requires boss of 8 diagrams soul

also it would be quite nice if you could resize the quest window to fit the quest name and lvl requirement.
