IDEA: Trap thinner fabrics behind embroidery to join to other cloths, without seaming. Layout the fabrics over one and another to make large ares. Tack roughly together. Machine embroidery over in geometric patterns. At rough joins, use embroidery thread to make decorative stitching over the joined areas. Traditional patchwork rectangles can change to any odd shape,i.e. the whole garment can become a work of art, a painting of colour with fabrics and embroidery.
