Ropes and lines
It's amazing what you notice when you look for it! Or perhaps, what you see when you hold up a particular lens.
After writing the post on Orla's schemas yesterday, I noticed her today pulling gleefully on the blinds, saying "Mummy why do ropes makes lines?"
The whole ropes/lines thing reminded me of my February observation. And of course, if you were interested in horizontals and verticals, then venetian blinds with vertical cords would be, well, interesting. Especially the effect of pulling on the vertical to make it longer.
