I have enough fine black yarn to knit a sweater. Any suggestion regarding a chart for this difficult color ?
I don't quite follow your question, but I can suggest you knit in good lighting, and use a white cloth on your lap to help you see the yarn/stitches against it as a background. I just did a shawl in black from a chart, but the chart was no problem, it was distinguishing the actual stitches because of the dark color.
And all the women who were wise of heart spun with their hands, and they kept bringing as yarn the blue thread and the wool dyed reddish purple, the coccus scarlet material and the fine linen. Ex. 35:25
