Okay guys this is how it works but since I have no idea how to put pics on here ill just type it...
What your obviously going to do first is get a knife from the Grand Exchange,
Next your going to buy Normal logs approx.. GO TO ANY BANK it doesn't matter. Cut them until your Fletching level is five.
Then go onto short bows once you have reached ten fletching go onto long bows. From there keep fletching till level 20.
Go to the grand exchange buy oak logs and go back to the bank and make oak short bows.. Once you reach level twenty five go right to oak long bows.
Once you hit the level 30 mark go back to the Grand Exchange and buy some willows back to the
Bank and go fletch willow short bows after that you should be 40 fletching in no time.
Once you got 40 fletching make willow long bows until level 50. Ten whole levels oh god im not going to make it!
Once you level is at 50 go to the Grand exchange and buy maple logs make the maple shorts until level 55 once at level 55 go all the way to 70 on the Maple long bows. This might seem like a long time but it is Well worth it (Maple long bows do not sell if you have a rare or good item use it as junk so you can lend things.)
Next you going to the grand exchange to buy yew logs and bow string. Id say buy 2k of each yew logs and bow string. your probably saying to your self this isn't going to make me money but it does.. cut the yew logs into yew long bows (u).
After your done that nonsense.. What your going to do next is kind of weird but you will get used to it as you go on.. left click ur logs and take out (14) it should say 14 every time now, take 14 bow string out of you bank as well as 14 yew long bow (u)'s this is faster than cutting the logs.
All I can say is thank you for taking time to look at my guide.
PS: don't string bows under level 70. Unless you want to be in debt, Also you can do this for magic long bows to(Don't use short bows for this method..) The reason I don't recommend this method to most players it takes cash.. for magic's
Cooking Guide coming out soon.. LOL Ill try to get pics in this next one.
