So I bought a lot of wool at very discounted prices (I am talking pure wool at $20 for about 2.2 pounds of yarn), but I was annoyed when I got it to find that it is super thin.

I have gotten to the point where I have figured out that a single strand of this particular 4ply knits up on a 2.75 mm needle!

Three strands work out ok on a 4mm needle. Suffice it to say that I will definitely be tripling, if not quadrupling, quintupling, sextupling or even septupling this yarn, LOL!
My question is, how do I do this efficiently?

I made three seperate balls but this yarn, which is unfortunately also squeaky to boot (grrr), got all tangled up. I thinking of combining the yarn first and then making it into a ball.
Any advice that you all might have about how I can do this efficiently would really be appreciated.
Thanks in advance for your responses.
