I was able to purchase the four hanks of yarn at a shop yesterday, so the lady wound them for me. I do have a shawl that I'm ripping out today, so I'm going to give this technique a try. I usually just wind the yarn back into a ball, but I'd like to have a center pull cake this time. I hope it works! I'll let you know!
Thanks to everyone for their great suggestions - you guys rock!
