I believe the herringbone stitch is a sewing technique to insert elastic into waistbands. I think you sew "around" the elastic (not through it) to keep it in place but let it retain its elasticity. I bet a sewing stitch site would be a good place to find out how it's done.
Here's a couple instructions with illustrations: Site #1 (Scroll down a bit) Site #2

"There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one of you in all of time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. The world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open. You do not even have to believe in yourself or your work. You have to keep yourself open and aware to the urges that motivate you. Keep the channel open."
— Martha Graham
I'd decided it was a sewing stiitch Yvonne but have been trying work out how to do it while incorporating the stitches I have on the stitch holders. I may have to cast off first although the pattern doesn't say to do that :rollseyes:
Thanks for the site info Amy - really clear instructions - I have used this for hemming before (while sewing that is). And thanks for the welcome too :D
