Sometimes I use pencil most times I use charcoal because a charcoal drawing blends in with the oil paint. I don't usually spray fixative on the drawing, just jump in and paint or paint over the lines with Liquin and thin paint to keep the under painting.
I dove right into the cheeries. Almost as much fun as grapes.
This arrangement is a little different. The star of the show is the cherries which have the only real darks in the painting. The rest is a very high key or in very light halftones.
I may do more paintings of cherries. You could say a series of cheery cherries is a chance for change. Check my choice tomorrow.
