My daughter received some art supplies from a relative for Christmas, only she doesn't like to work in colour she later told me. While grateful for the thought behind the gift, she didn't feel she could use it, so gifted them to me.
The charcoal pencils came unsharpened and fell apart when I tried to put a point on them, with two separate sharpeners and a blade. They weren't well made so they were binned. But she was also given a tiny A5 (8" x 6") sketch pad of black paper, the charcoal pencils were meant to be used on.
So out came my watercolour pencils for an experiment.
The thing with experiments is, you never know what you're going to end up with. I learned the limitations on such dark paper, with pencils. They weren't very vibrant. I used the watercolour pencils dry, so I struggled to develop highlights on a black background.
I tried to use a black marker pen, to get some detail in the leaves, but fear I only made it look more messy. You never know if you don't try these things out though. This was not meant to be my best work, just demonstrating the results of an experiment. Perhaps prisma coloured pencils would have worked better? I know with such a small pad, I cannot use my chunky charcoal blocks or oil pastels.
The inspiration was my luffa vines, which are sporting a lot of leaf cover at the moment, but no flowers as yet.
