Interesting now its finished; things I was expecting and others that are surprising.
I was expecting the iridescent effect to be light and directionally dependent, which it is, but was surprised that it's effect really comes alive when the fabric drapes naturally - making it great for a garment but less effective as a screen or wall hanging. As usual, the photo really doesn't show the sheen and glow but it does at least show the blending of the colours.
The close up shows it better and the extreme close photo shows the interlacement detail.
The background colour is black, so it has a very high contrast with lots in the blue and purple spectrum but, in real life, the yellow is the real standout colour which makes it glow.
There is much to be learned from this first piece
