Good for him! My boys can sew just like my girls can change the oil in their cars. This the day and age where it takes 2 people working outside the home to make a go of things. It takes 2 people working at home to keep things going there too. He is learning a life skill as well as a sewing lesson and math lesson and geometry lesson, too. He is also learning an even more valuable lesson.....helping others. Great job to him and to you for teaching him.
