This was made from two 22" Talon zippers that were unopened and originally cost 65 cents. They had weird brown marks on them so after I made the rose, I 'antiqued' it with instant coffee.
This was made from two zippers that she apparently took out of some article of clothing as many of the basting stitches were still in them.
These roses are quite large - the white one is about 3.5 inches in diameter and the red one is four inches in diameter.
I have lots of zipper inspiration and tutorials for you.
