Yipee! My 15-91 is a centennial, love it! It's so quiet and smooth...
I used mine to reupholster the table for my chiropractor. He bought very thick leather, imported from Australia. It was a full 1/4" thick when 2 pieces were sewn together. My machine handled it just like it was sewing through butter. I didn't even need to change the tension. I went from sewing cotton to 1/4" leather and back again with not a hitch. love this machine! (I did use a leather needle, that was the only change.)
