Gesso over Pastel and Colourfix?

[Sharon Knettell]

Brenda,

I use lead primed linen. Fredricks makes a good one called RIX.

The problem with painting oil over previous attempts is that there is the problem of 'pentimento', that is oils have a tendency to get more transparent with time and reveal what is underneath them.

I just talked about a cheap and archival substrate in the Masonite thread, cheaper and easier than canvas and more archival.
