Some fellow artists may find this useful. My latest travel log has some rubbish paper in it that doesn't take paint well. I will be using this to protect the paper. I also wanted to be able to use oil paint on card and think this will give protection to the card as otherwise the oil paint may eventually make it go mouldy. There are some photos of paintings I have tried and links to video instructions on how to make it on my google blog. Google gabriellasmith blogspot "capturing the moment" to find it. Hope you find it useful!
