This top hat is covered in polyester ultra suede with a sequined sash. It's the first time I've ever worked with ultra suede, and I love it. The stitches just melt right into the fabric giving wonderfully smooth seam lines. And it feels just like real suede. I'm definitely going to use ultra suede again for covering hats. This one also has some fantastic lime green sequined fabric for the removable hat band. It's the same fabric I wrote about in my post Sewing with Sequins. (My sewing teacher saved me a little piece after the dress was finished because she knew I adore it.) Since the sequined fabric is stretchy, it holds its position on the hat without any tacking, so it's easy to remove and change out with something else, just in case lime green sequins don't match the rest of your outfit.
