We had a beautiful work to frame from Glenys Cour. Just one problem, it was badly ‘cockled’ from the penetration of oil paints into the card. The top section was a modest roller coaster of humps. We solved it with Pva adhesive, laying it onto a heavier mdf board, putting glass over it and all the weights we could find. Next morning, flat as a horizon and ready for framing. So that’s what is was all about!
