So the fungus-inspired colourway of the last couple of weeks now has a name: Versicolour.
I've done a couple more now, one on white Southdown (crisp and bouncy) and one on oatmeal BFL (the colours more muted and subtler than on white).
Anyway, while I had the dyepans out I did a quick bit of Nightfall, over both black and oatmeal BFL/silk. Someone had contacted via Etsy regarding this colourway, so I put all four up on Etsy and she bought the one she wanted straightaway. The other three are still up there.
