Open up a zipper and cut off the bottom link part.
Please take note that the inner and the outer surface of the zip is different, and it will give different impact when you fold the zip using different side. You have to be consistent when folding the pattern. I prefer fold the zip face in (left one in the above picture).
Fold and press them together like making ribbons' flower. Fixed the shape by sew a small stitch on the area you hold when you happy with the pattern formed.
Create more - mix the color and pattern
Arrange them into the shape of a bib and sew them all together
sew both ends with some black lace ribbons or chain or rope...
Tied a satin ribbon on the where I combine the, just want the finish look to be neat.
You can use the rest to acessorized other stuff...phat, pin,...
There you have it! All done!
