There appears to be no Solstice hat this year (unless it's super secret). I haven't seen anyone with a Solstice hat, and it's not on the Winter Bash 2018 Hat list.
Where in the World hats that looked like Solstice hats appeared in the 2016 hat list, and they were fantastic!
Why not this year? Was it for lack of mention on Suggestions for Winter Bash 2018? Some other reason?
