You know what the problem is with making stuff up as you go along? Not knowing how much yarn it’ll take.
I was able to knit one ear (yes, that’s what that is, below) before running clean out. Options: ransack the scrap bin (glad I keep every little piece!) or undo a few rows of the hat to “borrow” some yarn. I’m not even going to consider buying more yarn at this point. For 9 feet? Preposterous!!
