I enjoyed this one.  Thanks, Jane!  I had been using pans after finding that I was consistently too dark using tubes.  I went back to tubes with this one and for sure, my nest was too dark initially.  I went over the marks with water to tone them down.  Surely I'll reach a balance in time.  I'm adding the blackbird eggs I did.  I used Winsor & Newton's Cerulean.  They are anemic.  It's the second go so that's the way it is.
