That's what my kids call it. It's also the day that they doing paintings at their daycare.
I assume it's Monday --> Moon --> water --> watercolor painting, if I have my correspondences right.**
I'll share some paintings we did at home the other day. Probably not on a Monday, but I'm sure you'll forgive me.
We use cheapo craft store watercolor paper, which we often cut in half. This time I went whole hog into Waldorf style and rounded off the corners beforehand!
Because I save money on the cheapo paper, we use the expensive Stockmar watercolors. What saves our budget is that it's concentrated stuff, which we dilute way down and store in little glass jars in the refrigerator for many future sessions. (Because they are made with natural pigments and binders, the diluted paint will start to smell very bad -- rotten egg bad! -- if left out at room temperature, especially the blues.)
And here's mine. I was going for a sunset over the Santa Monica Mountains kind of look. (Unfortunately they look like this right now because of more wildfires lighting up the evening sky. I had no idea about that when I did this painting.)
**There is a Waldorf cultural tradition that the days of the week have correspondences.
This is nothing new; alchemists and astrologers assigned planets for each day long ago, hence their names. (It helps to have a few foreign languages to see some of them: Tuesday (Tyr's day from the Norse) is Mars day -- Mardi in French. Wednesday (Woden's day from German) is Mercury day -- Mercoledì in Italian.)
And so there are also the things that go along with the days and their planets: colors (blue for Moon/Monday, red for Mars/Tuesday) and foods (Rice/watery on Monday, Oats/fiery on Tuesday) that Waldorf early childhood teachers work with in particular.
