This one was entirely palette knife play. I love the textures that resulted and am thinking a high gloss finish would highlight them well.
I'm enjoying my little cardboard painting experiment a lot. The fact that it's salvaged cardboard and the small size of the pieces make it very non-intimidating and easy for me to go to the table. Today was the first day I wasn't really happy with the results (pic to come tomorrow), but that's what it's all about... practice and play!
