Step 1

Cut three pieces of fabric to form the sides and bottom of your bag. The two side pieces should measure 40x42cm (1534x1612in) and the bottom piece should measure 40x40cm (15¾x15¾in).

Step 2

Take one of the side pieces and turn the top edge over by 1cm (38in) twice then stitch down to hem. Repeat with the left edge. Take the other side piece and do the same along the bottom and right edges. With right sides (RS) facing, stitch the right edge of the left side piece to the left edge of the bottom piece. Repeat with the left edge of the right side piece and the right edge of the bottom piece.

With the wrong side (WS) facing you, fold the bottom piece along its diagonal. You will now have a V-shaped piece, with the RS facing you on one side and the WS facing you on the other.
