Tape off half of the copper capillary (I did a larger piece so I had something to hold while I painted them). Do a few coats of your favourite colour and let it completely dry.
Next, you will "figure 8" the rope between the capillaries.
Take one end of the rope and make a loop, then secure it with double sided tape. Then take a simple piece of string, yarn, thread whatever you have and wrap it around the double sided tape, to secure the loop. I hot glued the end of my string on the backside of the loop once it was wrapped.
Here is what the end result should look like.
