Start by making a large pie-piece shape from the scrapbook paper. It should be in the shape of a triangle with a curved bottom
Roll it up into a cone, securely it with glue, and trim the uneven ends.
Using a round object that is about an inch larger than the diameter of the cone circle, draw a circle on one of the glitter paper for the hat bottom.
Using the same round object, draw another circle on the other glitter paper (you can use the same paper if that is all you have).
Use the cone to draw a circle in the center of the larger circle.
Cut the middle circle out
Cut small slits all around the bottom of the cone and fold the tabs outward.
Slide the circle with the center cut out over the cone and glue it to the outward tabs
Glue that onto the other circle cutout for the bottom of your hat
Cut a piece of ribbon to fit around the bottom of the hat
Cut slits into the ribbon so you can shape it to the hat by overlapping the cut pieces until it fits snugly around the hat
Cut out a square out of one of the pieces of paper for the witch hat buckle to fit over the ribbon.
