Badasscaps.com is an online-only, home-based businessin St. Clair Shores run by Grace McNamara.After she started sewing welder caps for her husband, a plumber, she realized there was a business in it, since his work friends kept asking if they could buy their own custom headgear. "Theywere so happy with the caps that I had a full-time job on my hands and Badasscaps.com was born," says McNamara. Now she sells a variety of head coverings to many other trades and even bikers.
