I'm using Tyvek for the first time in a project. In case you haven't come across it before, it's a really strong and smooth paper which is virtually untearable. Often things are packaged in it to protect them. It's really thin and cuts like butter - so it's great to use as there's no snags or fraying. I can get all the lovely detail in that I like without worrying.
So far I've done the 'N' and the 'A' and have started drawing out the 'Z'.
Here are the progress photos.
