I'm filling in the background around Luz's head at the moment, the light shading that's very hard to see even with a head torch... Here's the chart page cross reference image, and I'm still on page 3:

You can see the tip of the needle poking through the fabric in the top left of page 3, that's got the yellow background colour on it, and I'm 14 rows down from the top, having started at the top with the colour yesterday evening. The pink, grey & greens are complete, with only the light blue to follow in the top right corner of this page. It's nuts doing such sparse shading, but the effect is subtle and quite good. When I've completed all the light shading, I'll get onto the darker stuff just above Luz's head.
Just thinking about it, I am really pleased with this picture. Not sure whether I prefer this or Gryff. I really like both, otherwise I wouldn't have started either of them.
I've ordered some red 15lb monofilament fishing line (0.3mm diameter) and when it arrives I have a feeling I'll start gridding with it - as I get towards the middle of a page I end up spending an inordinate time counting from the edge to find the next stitch, especially if I get distracted & forget where the needle is.
Regards,
Richard
