Roll one A4 sheet diagonally from one corner to form a cone roughly 20 cm tall and 8 cm across at the open end. Tape the outer seam to hold the shape. Trim the wide open end straight if the edge is uneven. An adult does the trimming.

At the lower open end of the cone, cut a fringe of 1 cm wide strips about 4 cm up from the bottom edge, all the way around the cone. This creates the wavy hem that reads as a ghost skirt. Folds in the card make this slightly fiddly: go slowly and the strips will be even enough.

Draw a ghost face on the upper pointed section of the cone: two oval eyes positioned about 4 cm from the tip and a small oval or round mouth below. Keep the face in the top quarter of the cone.

Fill the cone with sweets from the wide end, then fold the top lip inward slightly or seal with a sticker. The fringe holds the cone naturally closed enough to carry without spilling.
