Road to 99 fletching

I thought I would go a little bit more in dept with what I'm doing, I know its nothing new but I like it because I like to feel like I'm multitasking while I play runescape, so for 99 fletching what I did is I Bought 28K total yew logs, flax, and nature runes. when I started

The logs are for making yew long bows which alch for 768gp the flax are for crafting exp when I'm done I should be around level 70 crafting, and the natures are for alching the yew longs. I decided to do yews because it worked best with the multitasking style that I like when I've finished my magic level should be somewhere around level 87 which is nice but the cake is that I can alch the yew longs at a profit.

 Yew long alch for 768gp each
Yew logs I bought for 350-400gp each I paid 350gp
Flax sell for 75-78gp each I paid 78gp
Nature runes sell for 118gp each

So I make a nice 222gp Profit for every bow I craft and alch. Plus all the extra exp I'm getting along with it.
