How do you level up your crafting on runscape

The easiest way to level up crafting in Runescape is to buy as much cowhides as u possibly can until u have about 1k left. Then go to Al Kahdrid(east of Lumbridge, South of Duel Arena) and tan all of the cow hides u have for 1 coin each hide. Then buy 1 needle and about 100 thread at the crafting shop on the east side of al kahdrid. Go to bank and with draw 26 tanned cowhides and have ur needle and thread out. Use the needle with the tanned hide and craft leather bodies, chaps,coifs and vambraces until u have tons of crafting xp.
lvl 1-30= 495 hides
lvl 1-50= 162,214 hides
lvl 1-80= 682,849 hides
lvl 1 -99= 6,793,283 hides
That's about 683 million dollars from cowhides to get from lvl 1-99!!! save up!!!!!!!
