I decided to do a little more detailed painting of Beach Ballerina on better paper (Arches 140 lb. cold pressed). As usual I didn't quit when I was ahead and tried to "improve" the tutu and I think I got it too dark. I tried to lighten it up by wetting the paper and blotting in places but I had trouble getting the white of the paper back. I then realized that I had used an Alizarin Crimson mix for the pink/purple tutu color and, if I remember correctly, that is a staining color. I also learned that if I wait a few days and let the paper dry very thoroughly, I can use a small battery powered electric eraser and lift off some color. I think I should quit at this point before I ruin it completely.
