I see a lot of gorgeous intricate pieces using all manner of right angle weave ropes twisted and angled into lots of beautiful shapes, but something I don't understand is how this is achieved when RAW is so incredibly supple. Some designs seem to rely on being attached together at many points and that makes sense, but I'm also seeing pieces with big distinct curves that aren't attached to anything. How is this achieved? The only thing I can figure is putting wire inside to hold the shape, but I see no references to this in the patterns I've looked through. Can anyone let me in on the secret, or point me toward resources to learn? I've googled with no success.
