Cut a long rectangle of paper.
Fold the paper in two places leaving a short middle section and two longer sections at either side.
Cut two more strips of paper that are slightly wider than the middle section and slightly higher than the two sides.
Fold the edges of the strips in so that the strips match the size of the middle piece.
Fold the bottom of the strips up so that they match the size of the sides of the main piece. Snip out the square made by the two fold on the edges of the strips.
Glue the bottom fold of the strips to the middle section of the main strip of paper.
Glue the folded edges to the side pieces and leave to dry.
Add handles out of ribbon, string or paper ribbon.
