I started out with a paper mache cone, which I covered with patterned paper from Pink Paislee "Twilight". The brim was cut from an embossed glossy cardstock with a Curvy Cutter by EK Success. I cut a smaller circle from the brim and inserted a snug made from a band of cardstock, allowing me to tilt the hat so the brim is elevated a bit in front when it sits on a table.
The fun part was decorating the hat! The fence and black cat are Spellbinders dies; I adhered metallic origami paper to cardstock before die cutting and embossing to get that marvelous electric blue. The pumpkin is a Bosskuts die and embossing folder set.
The witch tag and Mad Hatter insert are from Graphic 45's Halloween in Wonderland line. I used watercolor pencil to tint the Mad Hatter's hat. The Trick card is by Jenni Bowlin. The flowers are Prima. The key is from my stash, with a jewel accent.
I bought the bat die cut at a scrapbook store, but I think it's a Sizzix die. I used Stickles to accent the silhouette. The spider button is suspended with Divine Twine from Whiskers Graphics, which is one of our product sponsors this month for the Design Team at Cookin' Up Creations. I wound the twine around a pencil, sprayed with hair spray and dried with a hair dryer to get that curly effect.
I finished up with wired ribbon and some white tulle.
