I got the Satin cord on ebay, (used about 120 yards of silver, and about 70-80 yards each of aqua and light blue);
I used a tutorial on Youtube for the weaving.
When I was finished I coated it with a clear acrylic sealer / spray paint to protect it from the elements.
The chair is very sturdy ::: the weaving is tight and strong, and it's so pretty - hopefully it will last a long time. <3
