Loopy is constructed of 30 loops, each 10 feel long if unrolled, which are woven through each other and bolted together. The five colors are carefully arranged so that

- each loop crosses one loop of the other four colors,
- each color appears once around each 5-sided opening, and
- the ends of each loop approach the ends of two other loops of the same color.

For this piece, I began with a colored pencil sketch. Above is my first concept-drawing for the sculpture. I then made a paper model (below, left) so I could see it from different angles. (It got a bit squished before I got around to taking this picture.) Finally, I made a 13" metal model (below, right) so I could practice the interweaving and bolting sequence on a small scale. The final design doesn't differ much from the original sketch. The main difference is that I made the strips slightly wider to give it a little more body.
