3. Functions of the TWIX

3.1. The Zip system

Start the closing of the zipper on the bottom surface. Spread only the 3 middle cells and 1 or 2 cells
next to those cells. Thread the zipper on the bottom surface.
When closing the zipper lift the zip slightly and pull your fingers in front of the zip between the two
parts to avoid jamming of the cloth in the zipper.
After closing the leading edge turn the Twix on the bottom surface to close the top surface.
Before closing the last 70- 100cm of the zipper fold the ramaining top surface cloth to a triangle and
roll it in. Now you can close the last part of the zipper.
