Text on letters

I may have gone a little meta with this one. Text within text. What would the big text say? Who knows at the moment. What would the little text say? Well, at the moment I am very much stuck on continuous lines but that might all change. 

With the Rowhedge Art Trailing coming up later this year I want to think about large-scale text for an outside exhibition context. These text-on-letter tests might be the start of something. Though I am not sure the cardboard would cut it - they certainly wouldn't survive rain. 

I am also weighing up the natural colourings of the materials v's painted. The white on brown is growing on me and I am thinking that I'd achieve a similar aesthetic with MDF or similar - something that might survive the British summertime a little better than cardboard. However, I have played with white-on-black letters. A nod to the usual black-on-white text we are so accustomed to. 

The contrast is clearly more striking here, but I am not sure striking is what I am going for. I prefer understated. I also feel the white on black becomes a little too decorative, and the text is lost. I struggle to read the words here, despite being the one who wrote them. 

There is also something to say here about the amount of text each letter might hold. At the moment I am drawn to the less is more. I think I am persuading myself to go for something more readable, and less busy. I'm just not too sure what I want to say yet.
