I began solid prints #2 today and I think I'll leave them even longer this time, perhaps 9 days. I put them in extra wet this time and arranged them so all the fine swatches were placed on one side of the table and the thick ones on the other. I think having the thick ones beside the thin ones didn't allow for enough pressure on the thin ones, creating mostly an outline of the thinner ones.
I also think the madder and cochineal may not have many more prints in them, if even a second one. We'll see next week.
