Make sure you stretch the length of cord you're working with before you use it! This will stop it from stretching some later. After I pre-stretched the cord, I have yet to see anymore stretching from regular wear. With this thickness, a surgeons knot with some E6000 glue will hold very securely.
I LOVE this bead cord. It is great for making jewelry for children, since they can easily slide it on and off. It is also wonderful for longer adult necklaces and bracelets. LOVE IT!
I reviewed this product before purchase, it's a wonderful product!
This was so easy to work with. I made several bracelets with it and they look great. I would definately recommend this.
