DIY: Nautical striped yarn bangles

Ahoy! This DIY project I found over at katye elliot will have you in knots! See her handy tutorial below or visit Martha Stewart's original craft post.  

MATERIALS:
cheap acrylic bangles
cascade 220 wool yarn or cotton ( for year round wear)

HOW TO:
1. First, pick your first color and gather the yarn into a small ball. Tie a knot onto the bracelet and leave a long tail.
2. Wrap the yarn around the bracelet making sure to keep the strands even and tight; keep the first long tail exposed.
3. To change colors tie the two yarns together in a tight knot. The tighter the knot the smaller the bump. Trim the ends leaving two long tails.
4. Start wrapping with the second yarn to create tension. Drape the tails on the inside edge of the bracelet. Wrap the yarn over the tails. Hopefully the small knot will be the only evidence of a color change. Continue to wrap and change colors as you like.
5. When you reach the end secure the working yarn onto the long strand you have left dangling from when you first tied on. I clipped the ends and applied fabric glue on the knot and ends so they wouldn’t unravel. Don’t butt the two ends too close together. You want the knot to have some room to nest between the yarns and blend in.
