I was recently made aware of a typo in the TTN patterns (I spelled Q-Tip "cue tip" LOL) so while I'm correcting that in the PDFs, I'm going to adjust the directions in Santa Claus to move the loop attachment to the back of his hat, just above the rim (as shown in the photo above). At that spot, the glue holding the hat on his head should keep the loop from pulling the hat out of shape.
If you'd like, make a little note to that effect on your patterns. But you can also keep attaching it on his collar, if you prefer! The advantage with that is you can turn or angle his head without effecting the angle at which he hangs. :-)
