So I found this cool handmade hat at goodwill, but I don't recognize it as being either knitted or crocheted...so how is it made? It's reversible, and each side is differently colored:


Here are some pics of me flipping up the hat brim to show both sides together:


And here are some close-ups:


I know it's kind of old-school, but I really like how it feels and looks. It is definitely run-of-the-mill acrylic, but I'd like to make some in other colors and textures. The other thing that's cool is that the pom pom is on both sides. I think half of it shows through on either side. Also, the hat seems to be constructed as a tube that is cinched around the pompom on top. Is this made with one of those knifty knitters? Thanks for any help, fiber gurus!
