1 This mat uses 36 rectangles split into three columns of 12. Start by cutting several rectangles, 7cm x 13cm, from three different fabrics. Lay out the first column on a flat surface in a herringbone design with the rectangles slanting up, alternating the fabrics as you go. Start from the base of the column and stitch the short edge of the first rectangle to the lower edge of the second rectangle, with a 0.5cm seam allowance.

2 Open out these pieces and sew the lower edge of the third rectangle to the top edge of the joined first and second sections
