Spraying fixative over charcoal
Hi Leslie,
I probably can't be of much help here but I'll try. Recently I have been doing my sketch in charcoal on white canvas. Then I use KRYLON Workable Fixatif and spray over that charcoal. After as little as half an hour the fixative is dry and then I wipe on a wash of burnt umber and turp to get a toned canvas. Then when that's dry I start painting.
The fixative is amazing and prevents any 'rising up'. You might experiment with it and see how that works for you.
Hope this is of some help Leslie!
Joan
