I have been experimenting for handbag straps, I stitched these pieces out of piping. The first attempt I added 1 piece after another to the same side. It curved really bad. Then I did the circle, which was flat and great so I decided to see if I could build a side. It has a nice flair to it. The third I put 2 and 2 together and it worked best. Now I have to figure out how to cover them. I tried wrapping in fabric and even the "good" one did not wrap well. Good thing they look good "as is"
