I think those 20's style cloche hats are good for winter...keep your ears warm. ;)
Was looking to buy one...but spotted this tutorial on how to make one.
And thought..why not have a go. I have interfacing left over from another project...and some lovely fabric which isn't enough to make anything big but would be enough for hat.
If it works I'll buy some nice fabrics and do a proper one to match my coat.
