The screwiest ball of yarn I've ever seen: I tried to pull from the center, but after disgorging half of its volume it became clear that there wasn't an inside end. There were TWO! Picture two strands wound together just slightly twisted, not plied.
To make it a bigger PITA, this discovery was made in the car after our trip started. So instead of getting to knit, I spent the whole time trying to wrangle it into submission. Still not done.
When I got home, I was happy to find the other balls didn't suffer the same defect. I can't wait to see how the colors unfold in this scarf.
