What is a reasonably quick way to train up crafting in F2P. I have lvl 28 crafing and 5 mil.

Hard leather body's should be the fastest xp you can get in F2P, until then you can do like gold rings or something

Gold amulets are probably one of the best all round. Somewhat decent xp and guaranteed profit and sales.

Once you get alot of money you can game the ge and buy the uncut gems for low .. then wait and sell them when the cuts go up to the same price that you bought them for... gem cutting is the best :) Cut about 25k emeralds last spring

Gold amulets are good if you dont make much money, but for speed, making unsrtung symbols will give you 66% more xp (50 as opposed to 30) and will usually sell for a 2.5gp/xp loss (hint:they are used for lunar string amulet)
