I used acrylic paint instead of oils mainly because acrylics dry quickly. Painting on the reverse side is a slow process because there is a lot of turning back to front to check how the painting is progressing.

Having completed one of these acrylic panels I have to say that this technique is very messy - at least the way I do it - which gave me another reason to be happy that I chose acrylics. Cleanup is much faster than with oils.
I like the technique a lot...messiness notwithstanding :-)
