the pattern companies all carry learn to sew patterns now. That said, i've taught several kids to sew. Start with sewing on lined paper with unthreaded needle so he gets the hang of straight stitching, then have him draw a design with pencil that he likes on a plain piece of fabric and have him stitch that with colored thread ( a mini wall quilt), the progress to an easy sewing pattern. Get him a basic book on sewing so he learns to read patterns and knows about grain line, different fabrics etc. My girls used the Coats and Clark and Vogue Sewing books to learn and even now as their reference manuals.
