Thanks for these insights, and sharing what you have done with them i am always spellbound with the designs that predominantly pre metal and modern machine cultures came up with.The answers they found to solve problems , and the designs that show an in depth appreciation both of the material and the techniques developed to work with them . a lot of the designs like these ones i find much more appealing than some of the more intricate modern designs that machines help us to explore , they have an individuality , a sense of timeless permanence, and presence about them that is hard to replicate.
Cheers
