I was going to draw lines for the kites and tried the design on a scrap of paper with drawn black lines and didn't like it. I then went to my trusty string, it was a bit tricky to get the string on, but I think it gives a much better look. To get the string on I first cut it all to 1 length then tied it in a knot. Then I lined all the string flat on the card and attached it under the kites, cutting it to the length I wanted as I went. I hope this helps if you give it a try. All the colors of the kites are the 2011, 2012 in colors from Stampin'up.
So here is my card.........
