Remove thorns from the petrified forest and replace with something like a vine but is perhaps a silk thread/webbing thing.
Can harvested and turned in to string (9 in a grid = 1 string). Shears neded to harvest or it'll just break. Should be pretty poor return as it will be abundant. Has the same properties as webs and slow entity movement when collided with.

Changed it a little to be sheard to get string but it's implemented for now and the thorns are gone. Will probably need a new texture for this as it's a little too light in hue and could maybe be a little more 'dusty' to fit the WIP biome a bit better.
