I've now got my two negative covid tests and so we're back on Thursday. In preparation I've been priming some cardboard panels with PVA to make a less absorbent surface to paint on. This will be useful for acrylic as well as oil painting. If you have any unwanted board/mdf hanging around you can prime these too. If you are priming paper or cardboard it's worth doing both sides so that the surface remains reasonably flat. One coat, diluted 3 or 4 to one should do it.
it looks quite patchy but will dry clear.
See you on Thursday!
