Teach him. Be patient. for him to allow you to teach him is a big step. I have sewn for more then 30 years, until we began refurbishing sewing machines my husband had little interest. He now knows machines, techniques and terminology with the best of them. It was and is a big step for both of us. we have become dependant on each other for our various skills. It also will be good for him to see what you really are gifted at- it doesn't happen over night.
