Seems there's a fancy new part coming out soon. 1x2 place with hollow studs and rounded corners. Along with all the other neat things it could be used for, one thing I want to see it used for is some kind of flag or banner material. From what little I know of the techniques, most "curve" builds use a mix of 1x3 plates and 1x1 round plates or some staggered arrangement of 1x2s and 1x1 rounds. But the new piece looks like it could maybe provide a much simpler, better-looking, and more stable way of doing that. I'm sure it'll be good for other compact curve uses too, like cylindrical shapes.
Just want to get this thought out there.
