This workshop is right up my alley. The paper is really wet and scrubbed front and back and put on plexiglass and it will stay wet for hours. And we are focusing on dark and light patterns throughout.
In the ref photo you will see spurge which flowers in January here among prickly pear.
The teacher looks like and talks like my sweet sister in law Martha but with a mid texas accent rather than a North Carolina one. Love it!
