2. For the hat: Cut out four triangular-shape quarters, with rounded edges. Sew or glue the four quarters together, start with two of the triangles. Lay the two triangles exactly on top of the fabric with the "right sides" of the fabric, the sides intended to face outward, together on the inside. Stitch or glue from the point of the triangle down to the edge on one side of the triangle only. Open the two stitched triangles and lay a third triangle on top of the two stitched pieces, again right sides together; stitch on the third piece from the tip of the triangle down to the edge. Open up the fabric to lay down the fourth triangle and stitch it into place, right sides together. You will now have a solid piece of batting that is starting to curl and will no longer lie flat. Fold this entire piece so that the two remaining edges are on top of each other. Rather than adding a band and finishing the ends, we tucked the ends into a white sweatband.
3. Mask: Our ghost is a wearing a store-bought felt mask from Target ($1) that we doctored by cutting out the purple felt backing that showed and making the eyeholes larger.
Turn your sofa into a creepy masterpiece:
1. Start with ripped cheesecloth ($2.29 a pack for 2 square yards) (we used two packs) at Michaels.
2. We added one orange throw pillow ($15) at Bed Bath & Beyond and one black throw pillow decorated with a skeleton head ($13) at Target.
3. Complete your scary look with a large black spider ($8) and rats ($5 to $8) all from World Market.
