Just finished my challenge quilt for the word CELL. Boy this was a hard one for me. I finally decided to make a quilt showing the surface (photosphere) of the sun. What you see on the surface of the sun are dark and light spots which is called granulation. This is basically showing the convection cells that are taking place right below the surface. The bright spots are where the warmer gases are rising and the dark spots are where the cooler gases are sinking. Of course the colors in my quilt are not true to life nor did I work from a photo since I did not want it to look realistic.
Here is Chowder helping me quilt earlier this month.
And here is a photo taken of the surface of the sun showing the granulation.
