Writing about your work is such a valuable tool. I wonder whether most of us use it often enough? I am sure that I don't. Writing my last post really helped me to clarify in my own mind what I was doing (obvious really, if I am going to explain it to you!) and this helped me see where I was getting caught up.
I've been a little too anxious to use the solarplate technique for everything, just because I wanted to use it. It's far better to look at the creative problem that you have and then decide the best possible methodology that you have at your disposal, and this definitely includes the media. This was always clear to me with ceramics, which was my first media. It's simply not good enough to say you are making such-and-such from clay, because that is what you do. The choice you make is so much more important to the work than that.
So, I realized there were other, more effective ways to depict the sky in the way that I am looking for, and I have started to test them out. Monoprinting is a very free way of working that really appeals to me, despite the fact that I don't have a background in painting, as many monoprinters do.
I used the new Golden Open acrylics on paper and perspex for these. Some of the perspex ones have added acrylic and drawing. Some of these look more like water than the sky, but that's all right. They were great fun to make, and lead me in a variety of directions, as well as coming much closer to solving my original problem.
