Not my pic, but I found a pretty cool store on Etsy that sells horse hair hat bands. I got one of those for my hat, too. Great deals, and it cheers me up personally to decorate my hat. Going /out/ is not the same if you have nowhere to tuck the feathers you find.
If this thread is still around when I get my stuff in the mail I'll post a pic of it all together.
