Twisted braid can be finished in several ways.
If you do just blank cord, which subsequently will be cut into the elements that tie all the straw netting in one tight bundle, this way you will lock the weave.
If you have a decorative shape, such as bell, you need to leave a hole in the netting open. Associate working together with a straw culm under her, as close as possible to the point of bending and cut all of the straw protruding at the level of the corners. Cut place fix it with glue.
You can bring working a straw under the bottom layer of the weave. Along the whole perimeter of the straw in this case will be braided in the cross-section. Trim the protruding ends of straws around the perimeter of the section and secure the sections with glue.
