Step1
To start, you need a Runescape account. Runescape is an Mmo Rpg (massive multiplayer online role playing game) and has over 6 million players. Which means there is a large community of players who are having fun.
Step2
These levels will go by fast and won't make you alot of cash. But you will lead on to bigger and better things quickly.
GlovesLevels 1 - 7: Make leather gloves, approximately 48.
BootsLevels 7 - 9: Make leather boots, approximately 20.
CowlLevels 9 - 11: Make leather cowls, approximately 22.
VambracesLevels 11 - 14: Make leather vambraces, approximately 35.
(the map to the right is where the cowpen is where you can get cowhides)
Step3
Here's where the money comes in!
Levels 14 - 58: Spin bow strings, approximately 15,883. You can either pick the flax or buy it for 100 to 110gp each. Bow strings sell for 180 to 200gp each making you a nice profit. The best place to spin flax is in Lumbridge Castle.
If you spin 15,000 bowstrings and make 170 of each of them you are making a total of 2,550,000 gold (that's 2 mil)
Step4
Levels 58 - 66: Make Earth battle staffs, approximately 1,470. Battlestaffs go for about 9000 each. But your not through yet there is still 1 more task and a lot more money to come!.
(the map to the left is where you can find seaweed respawns, which you need to make battlestaffs)
Step5
Levels 66 - 99: Make Air battle staffs, approximately 59,706!!!
As I said these go for 9000 each (give or take 100) Which means that's alot of money (I'll let you grab a calculator and find out just how much yourself!).
