Time to think of some ideas...since the simple block M was out of the question. I stupidly chose to make mine out of coffee stirrers/sticks. Something I regretted up until the moment it was finished, but now I'm quite happy with the result.
I wanted the end result to be quite colourful and to stand out in this wall of type instead of just blending in with whatever else was to be made.
So 1000 coloured sticks later I ended up with my finished letter! (yes I did paint them all...bad times)
