I pushed hard this evening and cut the rest of the pluses I need, chain pieced like a demon, AND labelled all different colours. I went with A-H and 1-11, so that’s 19 different shades of orange. 19!
Quantities of each colour vary from only one to maybe twelve? of a particular colour. I tried to keep it balanced so that no one shade will overwhelm. We’ll see if that happens tomorrow night when I do the big layout!
