bugle bead structures
A few days ago, I wrote a post about the trouble I was having making structures out of long bugle beads, because of the sharp edge of the glass bugle fraying the fireline. Gwen commented saying that when she uses bugle beads she adds a seed bead at each end of it and treats the group of 3 like a single bead. I said that might be an answer. Actually, though, it sounded to me like too many seed beads. I was adding a single bead between each bugle, so as to make a slightly truncated tetrahedron. The small flat face (a triangle of 3 seed beads) at each point of the tet added a bit of wobble, but not too much. But it seemed to me, thinking of the first triangle you'd make in the tet, that doing it Gwen's way you'd be adding 2 seed beads between each bugle, and so you'd be adding that many more seed beads, and it would get more and more crowded where several tets meet. Gwen, I hope you read this, because you were totally right and I was totally wrong. Turns out that as you keep adding tets, it actually gets less crowded. I can't explain it, so I took a picture. There are 2 structures, each consisting of 3 tets The 1 on the left was done "my" way, making truncated tets. The 1 on the right was done the other way. Each one has 3 seed beads at each point where 3 bugles meet. So that by even thought your 1st triangle has 6 seed beads in it instead of 3, by the time you've finished a whole tet, the total number of seed beads is the same either way. More importantly when 2 or 3 tets share elements ( in these the bugle bead in the center is part of all 3 tets) the structure done my way has 7 beads at the top and the bottom of that central bugle bead, and you can see they kind of bunch up. When I did it Gwen's way there are only 5 and it all fits together much more neatly, even using #8 seed beads. That's good for me, because, especially when I use the 30mm bugles, using #11s at the ends just doesn't look right to me. To my eye a bugle that big needs a bigger accent bead. Even here, with 20 mm bugles, I like the 8s.
