Actually, the technique is very old, referenced as "bishop's scarf" ... I learned about it on Sew Perfect a bunch of years ago ... guest was:
Linda Maghee ... I used the technique to use in foundation pieced vest ...
however, the newest book I have found is called Tube Piecing (?) been awhile since I have seen my copy <g> ...
and, the author has done some amazing things with the technique.
God bless those souls who must look to the skies, when the rest of us are willing to settle on the view at our feet! LOL ...
now, to go find the book! <wave>
