Thank you so much for your all your compliments, makes me feel great! The pattern is by Brenda Henning from her
book Indian Summer by Bear Paw Productions. The use of the twin needle does make a pattern on the reverse side which looks a little like serging. I have used the twin needle more and more for topstitching. The only thing you need to watch using it on this project is the width so that the width of the two lines of stitching suits the width of the bias tape. My class is in Glendale, Arizona, on the west side of Phoenix. Thanks for asking, all of you, you flatter me!
