This mod lets you turn plain white wool into 4 string.
As far as I know, nobody has made one of these that is updated for 1.7.10
So I did it.

PLEASE REPORT ANY ISSUES WITH THE MOD!
Does it work in 1.8?
I want ocean content(thanks Möjang!), nether biomes, and savanna passive mobs.
1.7.10 only right now, updating once the tool I use works with 1.8 code.
