My second wristlet and I used a nylon to construct this one.  Someone gave me a few skeins of yarn when I visited their non-profit and low and behold this novelty yarn blended in with the nylon.  I am beginning to do more and more weaving into finished crocheted pieces and this yarn was perfect. Instead of putting magnets on the inside for folding, I had to put the magnetic snaps on the outside because the magnets would not adhere.  9" X 9"
