Fold a square sheet of paper four times – twice in the middle of the sides and twice diagonally (drawing a). Then fold the card like this, to get a smaller square – drawing b, and the free vertices A A’ of this square are on top (drawing c). Bend these vertices like this, to touch vertex B (drawing c, d). AA vertices’ fold into a narrow strip three times, thus creating a pocket, into which you put the handle of the basket (drawing e). Then, together with the handle, bend the AA tips again’ to half a square (drawing f). CC vertices’ bend inside (drawing g, h, i). Bend the tops to the sides like this, to form a basket (drawing J).
