I do...when I got the janome 6600, I took a piece of scrap fabric, and didn't stop until I learned how to use it correctly....you will be so glad you did too...try it..start slow and work your way up...it only takes a few tries to get it right..this leaves both hands free to hold your fabric. And the knee life, same thing..try it until you get it right...they are both wonderful options for sewing.
