Sunflowers: Work in progress

Linocut, 18 x 18 cm.

I use far more white ink that any other colour, so always order two tins at a time, to make sure that I don’t run out. But when I opened the white ink tin this morning, it was almost empty. And the back-up tin has disappeared. Or perhaps this is the back-up tin.
So this block is printed just in black relief ink, and then hand-coloured with acrylic ink.
P.S. Have just ordered more white ink. Why has the price gone up 40% in a year?
