Best used sewing machines for leather?
I'm planning to sew some pieced leather pillows and recover some couch cushions with a medium-weight leather. I have a few, old, domestic Singers that might do the job, but they're not walking foot machines and I worry that they might not be strong enough. Does anyone have experience sewing on "leather machines?" If so, which machines can you recommend for the home sewer?
Thanks,
C
