My introverted thinker daughter is somewhere between 7 and 10 years old when she says that she wants to paint a flower.
My mother was an artist, watercolors, etchings, oils, lithograph, drawing... not acrylics. But I learned a lot just watching her and I always have art supplies.
I get watercolor paper and paints and water and set my daughter at the kitchen table.
The IT eyes the paper and doesn't touch it.
I wait for a while. "Do you need something else?" I ask.
"Yes." she says.
I get a flower from the yard and put it in a vase.
"Here. You have a model."
She sits frowning at it.
After a while, I try something else.
"Here is one of my mother's watercolors. You can copy it." My mother painted lots of flowers.
My daughter does not stop frowning. After a while she says, "No, that doesn't help." I take the watercolor away and the vase away and wait.
She brings me a painting of a flower. She is all smiles and satisfied. She explains: "I wanted it to be perfect, but I knew I couldn't paint the real flower perfectly. I couldn't copy Grandmother Helen's painting perfectly either. So I painted a flower that I imagined and one that I could do perfectly."
Problem solved.
