Unravel each piece of 8mm cord into three separate pieces and pile them on top of one another.
Choose the 2mm cord colour that will be the inner arch of your rainbow (blue for us). Fold the 2mm cord in half about 8.5 inches from the end. Then place it on top of the pile of thick cords so the loop is 1 inch past one end and the end of the blue cord is 1 inch past the other end. (Don't cut the blue cord.)
Press your thumb onto the coloured cord to hold it in place. Then wrap the long end of the blue cord (attached to the spool of cord) around the off white cord, leaving 1 inch of off white cord showing at the end. (Those will be the clouds).
Tightly and evenly wrap the blue cord around the off white cord, being careful to fully cover it with the windings.
Wind the cord until you reach the other end of the natural cord, again leaving about 1 inch unwrapped on the end for the clouds.
Cut off the coloured 2mm cord from the spool, leaving about 2 inches extra.
Put the cord end inside the loop you created at the beginning. Now pull the cord from the other side (where you started wrapping).Pull until the loop and cord end disappear inside the wrapping, and then cut off the extra cord as close to the wrapping as possible.
Bend the wrapped cords into a curved rainbow arch. Your inner arch is complete!
Step 3: Make the middle arch
Cut 2 pieces of 8mm macrame rope to 7.5 inches.Follow the same steps as with the blue arch - Unravel the rope into 3 pieces each, then lay out the next colour of 2mm cord (we used yellow) on top so that it's folded on top of the off white rope with 1 inch hanging off at each end.
Before wrapping, make sure you measure the arches against one another to make sure the cloud tails are the same length.
Wrap the middle arch the exact same way as the smaller arch. Be sure to measure the arches against each other again to make sure the other end's "clouds" match as well.
Finish off the center arch in the same way as the first, pulling the loose cord inside the wrapping.
Step 4: Make the outer arch
To create the larger, outer arch cut 2 pieces of 8mm macrame rope to 8.5 inches.
Repeat Step 2 to make the largest, outer arch and be sure to measure it against the center arch as in Step 3.
Step 5: Attach a hanger to the red (largest) arch
Cut a 12 inch piece of 2mm cord to match the outer arch (red, in our case).
Tie the middle of the cord around the top, center of the outer arch with the loose ends pointing up and away from the arch.
Attach a wooden bead onto the cords and then tie them in a knot to create a hanger.
Step 6: Connect the rainbow
Use hot glue to connect the rainbow arches. Begin by applying a thin line of glue, about 2 inches long, to the center inside of the largest (red) arch.
Press the second (yellow) arch onto the glue, making sure to line up the ends of the windings.
Continue adding hot glue every couple of inches until the two arches are completely connected.
