I fixed the pom-pom a bit: using a yarn needle, I pulled some extra yarn bits through the "seam" to disguise it. It looks much more acceptable now.
I wouldn't want a homeless person to have to suffer an inadequate pom-pom. The indignity!
Did I mention that there was no weaving in of ends on this tuque? Two ends became the ties (braided with extra strands), and the final ends tied on the pom-pom. I don't actually mind weaving in ends, but I thought it was a cute touch. ;)
