Runescape - How to make money?

what i do is go to a very filled world and sell capes at 2k each and i sell dyes for about 5k (because some people dont know how to get different colored dyes like purple or green.

The best way to make money, was killing green dragons Collect the hides and bones + any items droped by them. Hides are like 1.5k and dragon bones are like 1.5k bank and head back to green dragons and soo on till you have the amount of cash you need. But since your wondering how people can have Millions of cash to buy Phats, most of them played since runescape's first opening. Others merchant, and some stake.

if you area a member you can make steel bars and make cannon balls or just simply sell the steel bars 600 each or more if your lucky. say 1 iron ore for 100 coins. 2 coal at 180 coins each thats 460 coins worth of ores to make a steel bar which in turn you sell 600ea. This gives you 140 coins profit with each bar you make that you sell ( also 15 smithing exp per bar you smelt.) the other way which is much better money-wise is to make cannon balls after you smelt your own steel bars. 1 steel bar can make 4 cannonballs which sells 200ea. so 1iron + 2 coal=460coins. This is made into a steel bar which you make into 4 cannon balls. 4 cannon balls =800coins at 200each. thats nearly twice the money!!! and don't forget at the same time you are earning money you get exp from smelting the steel bars and also from making the cannonballs.

Another good f2p way is to go to Port Serim Rune Shop (or maybe Aurbury) and buy all the deaths there, and keep world hopping and buying until u collect 1k or more (highest price for deaths is about 223 gp) and then go to World 1 west varrock bank and sell for 300 ea!) Another good way is to buy (or mine) 1k or more iron ore, and 2k or more coal ore. iron ore is 100 ea and coal ore is 180-200 ea. u can also go to nooby f2p world in like fally and buy iron for like 50 ea and coal for 100-150 ea. so cost for 1k iron and 2k coal (100k + 400k = 500k) then smelt these into bars (smithin exp!) and sell for 600-650 ea on forums. Another way is to buy lots of rune ess (the higher ur rc lvl the better) and buy like 5k+ (my rc lvl is 46 so i get 5 air runes per ess) and make airs runes out of it! example (5k ess = 100-150k) and 5k airs makes 25k air runes (for me) and 25k airs sell for 20 ea, thats 500k! and runecraft exp!!
