Like everyone said...give it a go. It just won't be easy. But then again, you might be better than me. If that fails, just do a normal straight stitch and turn inside out. You can also do a straight stitch, and then hand stitch the flat fell part.

Last year for our tax return, I got my wife a Pfaff Ambition 1.0. It has been a dream, except it won't do supper heavy stuff. Sometimes I wish I had a heavy duty machine. I have my brother on the lookout for me. He is a sewing machine dealer and got us the Pfaff at wholesale.
