When I was in Arizona for Memorial Day weekend, I taught my grandson and daughter-in-law how to make the looping wire sculptures like Ruth Asawa. I had gathered all the materials I would need and brought them with me. The dowels were the easy part. Home Depot has 4-foot long dowels of various diameters and will cut them to whatever lengths you want. The wire was more of a problem. Home Depot had wire that was much thinner and much thicker than the 22-gauge that we used in the demonstration by Asawa's daughter Aiko Cuneo. Amazon.com has wire of all sizes and composition, but there wasn't time to place an order with them. (It'a amazing what you can find on Amazon!) I finally found some galvanized 22-gauge wire at JoAnn Fabrics and that is what we used.
My grandson really enjoyed working on his project and decided to create something of his own when he finished the basic bowl. He decided it was really a bird's nest and formed a bird out of wire to sit in it. My daughter-in-law turned her bowl into a candle holder. I was curious to try Asawa's technique of flaring the wire out and then skipping a row to see what would happen. My finished project serves no purpose whatsoever, but it was fun doing it!
