We finally had some success with a two sided tile. Our strings wound up being too loose so we didn’t get any definition from them, but that’s a pretty simple fix. Now it’s a matter of figuring out our frame system to vary the shape as well as really nailing down our attachment/dowel system (and filling that pesky gap on top). Our latest iteration was in canvas, but I’m not ready to let go of the tin foil. The nice thing about the canvas here is that we can control the tightness, which keeps the bulge from completely occupying the bottom portion. I think the edge condition between the form and canvas is really interesting too. Anyway, here’s some images of what we’ve done.
