Live and learn
Over time I've developed a sort of rule of thumb. With round beads I don't much like structures that use triangles (i e circles of 3 beads) because too much thread shows. Particularly I don't like to use monofilament nylon fishing line and have 3-bead circles, because it won't pull tight over such a hard bend, and so lots of it sticks out. I do occasionally do cuboctahedrons, which are a mix of 3-bead and 4-bead circles, but I tend to avoid them when I can. Similarly, with long narrow beads, and particularly with my metal tubes, I mostly only use triangles, because that's the only shape that will stay rigid with long beads. So I have lots of tetrahedrons and octahedrons, because they're made of triangles.If you tried to make a circle out of 5 tubes, it wouldn't stay round, but could take most any shape. When I have used 4-bead circles, I've always kept the cross section a triangle, because then, even if the squares turned into parallelograms, it still couldn't completely lose its shape, and it would remain 3 dimensional.
However, I've come to realize that while a single cube made out of tubes is pretty apt to not stay much like a cube, a series of them will have more stability. Also, when I was using oxidized copper tubes I used fireline thread, because there wasn't enough room for monofilament, which is fatter. But the silver tubes, although they're the same size on the outside, seem to have a thinner wall, so there's room inside for more thread. So here I used monofilament line to support the corners of the cubes better. The piece moves alot, but it still holds its shape quite well. It's big, because I wanted it to just go over the head without a clasp, so the pieces that form the long side of each rectangle are around an inch. Anyway, I enjoyed doing it, and may do more along that line. One thing I'd like to do just for comparison, is a simple rectangular necklace like this, but made out of a string of octahedrons instead of cubes. Then I can see whether a much more rigid piece works as well on the body as one, like this, with more give.
