@caribou,
So now you have instructions on scarf tying Roberta. I expect you'll be spending quite a few moments trying out the different styles in front of your mirror.
But hats: You can have a lot of fun with hats!

I suggest a few visits to a few different opportunity shops (Thrift shops, I think you call them). It's an inexpensive way to do a bit of experimenting .... & not
too much angst if you decide you don't exactly like what you've purchased, after all.
I'm thinking: Hats for Roberta. NYC in Autumn (your fall). Hmmmm ... what sorts of hats for that season?
