We found this great idea for friendship necklaces at HonestlyWTF and just had to share. It may be a little time consuming but it's worth the effort.
You will need some piping cord and a selection of threads to make these lovely necklaces, it's best to keep the threads all the same thickness for an even finish.
The technique is a basic Macrame stitch. Start by fixing the piping cord to a solid surface eg. the back of a chair or a cup hook or door handle you get the idea. By fixing the cord it enables you to keep the tension and makes knotting easier, the thicker the thread the chunkier the finished necklace will be.
Follow the instructions below and make plenty they look great grouped together.
Lay the color that isn’t being used (shown here in purple) in your left hand, along with the rope, and hold them taut. Take the active color (shown here in red) in your right hand, pass it over the rope, loop it under and back through the opening. Pull up and to the right to tighten. Repeat the knots until you are ready to switch colours.
To alternate colors, simply put the inactive color (red) in your left hand and the new active colour (purple) in your right. Repeat the steps.
Once you’re done knotting, add a few nuts and/or washers to the necklace. Undo the large starter knot and tie both open ends together, creating your very own friendship necklace! Trim any extra rope and tread.
