new skills for craftsmen

[Sudoku_killer]

so you think , in my opinion this would be fix for it
Having this possibility would mean that no one  would have to sell his crafted items at lower prices than production costs as it happens now. What for if you would have choice to retrieve mats and use them for new crafting or sell them and get back what you did put in that item. Market would not be damaged at all coz prices of mats would define items prices and that would be dynamic as market is

There is only one argument  against it I can think of , it could be used to  increase  xp by crafting same item multiple times unfortunately strong one,
