Answer:
I'm not really more than holes tied to more holes; I'm strong as good steel, though not as stiff as a pole.
I have green hair a round red head and a long thin white beard.
The more you take away from me the bigger I shall get.
I move without wings between silken strings. I leave as you find my substance behind
I begin and have no end. Eventually, I will be the ending of all that has begun. What am I?
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
