Hi folks, I thought I would post a link to Susan Harvey's Petite Boxes Scarf.  She has a great example of how to modify your beginning and ending treadling with a bonus of changing out your weft color to frame your scarf.  She explains in the project comments what she did.  Thank you to Susan for permission to post a link to her scarf.  It is a beautifully simple but elegant way to begin and finish your treadling pattern.  regards  Deb
