‘Whitewash paper’ sounds strange, but that’s exactly what she does in her tutorial with the decorative paper: she tints stripes of the decorative paper so that the original pattern shows through.
I find it very elegant.
I think that should be possible with gesso, too (as are so many other things: Wow!) – but I still have to try it out.
If you have experience with this I’d be pleased if you post it in a comment (by the way I’d always be pleased if you comment ;-))
