I did it for 15 years and burned out. All the deadlines!
I machine quilted for a business, made quilts for fabric companies, taught in a quilt shop, lectured, workshops at guilds, and worked in the quilt shop 4 days a week which kept me grounded. I was always tired and my relationship took a tole, I was always sewing, even as a passenger in the car.
now I work a real job and I feel like I go to work to rest because I am still doing the quilting for others, lecturers, workshops, classes at shops.
