First, cut two squares out of red and the blue fabric. Each square should be of the dimension, 15X15 inches. Draw four parallel lines 1/2 inch from each side. Fold the sides inwards and sew them.
Mark 3 1/2'' (9cm) inside from the four sides and draw lines. You will get a square in the middle. Measure the dimensions of the four long rectangles and of the square inside and cut pieces out of the cardboard of the same size.
Stick glue on one side of each cardboard piece and adhere it onto the fabric. Make 8 strips of fabric and arrange them perpendicularly and stitch to the sides along the drawn lines.
Place glue onto the cardboard pieces and adhere the second piece of fabric above. Mark 3 1/2'' inside from the four sides and draw lines using a pencil and a ruler.
Sew around the square and along the four lines that form the base of the basket. Fold the sides up along the lines and tie the strips in a bow.
