I should have said before but the reason I posted the photo of my mother’s painting yesterday was because I had been reading Andy’s (Patterns That Connect) article. https://patternsthatconnext.wordpress.com/2015/01/20/chance-and-order-at-eagle-gallery/. I do so wish I had seen that exhibition.
Here’s another of her paintings from the mid 70s, similar in theory perhaps to Andy’s intricate paintings from 2015. A fascinating link to four decades ago.

Hi Sally thanks for sharing this wonderful painting and for your (too) kind words! there are some amazing resonances here, though I think your mother’s painting is better than mine. What are the dimensions and medium?
Andy I think your paintings are great, really took me back to my mum’s work. I believe this is the only hexagonal painting she made, you’ve moved on a long way with yours.
The painting is in designers gouache on cream mount card and framed with aluminium L section. It is 40 wide and 46 cm high. She drew it all out in pencil and then painstakingly painted each triangle independently, even the borders, which are one colour. Such patience!
