Yup, I'm currently working in a space which just doesn't allow proper photos once you go beyond a certain size.
It did eventually occur to me that I could venture into the (unheated) conservatory; not something I am normally keen to do at this time of year. Actually, thanks to the ridiculously mild winter it was not too bad and I managed to get one photo of the bottom two thirds - though I had to hold the camera at arms length, above my head, and just hope for the best.
The tricky thing with putting this together has been that while the bigger curves came into being largely as a way of making the smaller units larger, and hence are entirely there for a practical purpose, I want some control over where they sit within the quilt as a whole, so that they look right to my eye. I've too-ed and fro-ed and have added one curve that isn't at all necessary (not visible in this picture) but am reasonably happy with the piece in the photo. I thought maybe the large curve on the right hand end needed to be moved, but am waiting to see that it looks like when the top row is ready before I do anything drastic.
With a fair wind this will be done by the end of today.
