I started out with a plain black top hat and glued on layers of felt to make it flare out at the top, just like in Mina’s tutorial. Since I wasn’t happy with any of the gold sequin fabrics I found locally and there wasn’t time to order any, I decided to create my own wavy-line sequin fabric by tracing lines onto fabric with a cardboard template and gluing strings of sequin trim onto the fabric. (NOTE: Once I was finished, I decided the sequins weren’t close together enough so I added more sequin strings in the spaces between them.) I’m not sure how many yards of sequin trim it took—I just bought a spool of 100 meters and still have plenty left over. I chose a lightweight, semi-sheer cotton/silk lining fabric layered over a yellowish gold poly-cotton broadcloth, since that was the only way I could achieve the color and texture I wanted with the fabrics available. I used my very most favorite glue, Gem-Tac. I made three large ovals (one for the flat top part of the hat, one for the underside of the brim, and one for the top side of the brim) and one long rectangle (for the stovepipe part of the hat). Be careful to make sure the nap of the sequins are all going in the same direction!
I glued the sequin fabric oval onto the top of the hat first, pinning it in place while the glue dried. You can see I made cuts through the center of the brim fabric pieces like a pizza—this is because on the top side of the brim, you need to wiggle that piece of fabric from the top of the hat (which is wider) down to the part where it meets the brim (which is narrower).
