I made this over-sized cross stitch at a craft night with friends a while back. All you need is a canvas, paint, embroidery thread, and a needle. First, I painted the canvas a metallic copper color and let it dry.
I then chose a cross stitch pattern I liked, enlarged it, and printed it. You may need to print it on several sheets of paper then tape them together, depending on the size. I put the pattern on the canvas and used a pin to poke holes through the paper and canvas at each corner of the squares in the design (where each "x" would go).
