To get a purple bag, this recipe<sp> is a little off...you need:
1-High quality wolf skin
1-High quality bear skin
1-silver thread
1-Backpack pattern
1-Light blue dye
1-Light grey dye
A light blue alone will not give you purple, have tried and it just doesn't work. Light grey is easy to make, 1 black extract + 3 resin. Just a heads up. I have sold about 150 bag to this point, so lots of combo's. Thanks
