I wrapped up simple rope I borrowed from work with embroidery thread using your standard friendship bracelet technique.
Knot your choice of embroidery threads around a rope.
Pick your starting color, keeping the other threads alongside the rope.
Pull the thread to the right, then bring it across the rope, making the number 4.
Wrap the thread behind the rope, bring though the four, and pull tight.
Repeat, repeat, repeat
Once you section of the first color is long enough, put it back with the other threads and pull out another color and keep wrapping/knotting away.
Tie all the threads around the rope and double knot when done.
Once I had enough wrapped rope, I tied it into a chain sinnet , glued the open ends together, and wrapped it up with more thread. Take that anthropologie!
PS: For the hot pink one, I hot-glued on bead caps to the end of the rope and attached to a chain.
