I have a 1964 model Kenmore. It has been used to make my son's clothes, (he was always hard to fit with "store bought clothes) my clothes, bridesmaid dresses for several weddings, stuffed toys, and now piecing quilts. It will sew thru denim and such fabric with ease. It is my go to machine. I agree the bobbin loading is a problem... especially with my old fingers. Even tho I have a light weight machine that I use sometimes, I love my old Kenmore best.
