Anything other than a straight stitch seems really weird on a 27 to me... probably because my 27 was bought when I thought she was just furniture and never thought she'd sew, never mind do more than she was designed for.
Jeanette, Every time I used to do a buttonhole with my 290C (my first sewing machine - second if you count the Holly Hobbie toy...) and its 4 step buttonhole, I got a weird trapezoid. Every. Single. Time. When I discovered the attachment and did a little reading about the, I had to try them. Loved them. I don't think the 290C was around long after that either coincidentally.

I agree with Rodney, it's best 2 times around but make sure you stabilize well or it can chew up the fabric quite a bit with that many close stitches.
Rodney! I think regrowing a leg is much faster if they use the starfish protocol.... did they do that?

I hope that a surgical procedure is better swelling wise than the impact damage DH suffered. Going on 9 months after the accident, he's still swelling. One thing he has been finding (and it's backed up by the physio therapist) is that a little "over doing it" once healed enough is actually good for healing. He pays for it the next day in aches and a little extra swelling but it seems to have accelerated his healing so far to do spurts of work with his leg. I think it's about circulation helping the healing.
