Researching plant fibre papers

In order to justify our paper idea, we wanted to find some plant based papers.

This is what I found on Alibaba:

I also found this really cool seed paper that whilst not being a plant fibre paper, was a sweet idea.

The Papermill is a NZ company that handmakes plant fibre papers. We spoke to them to find out about the process and the machines etc that they use to make it. They were really lovely and we are enquiring about getting some of the paper from them so that we can feel it's tactility and show the lecturers. They also said that the plant fibre papers are quite flexible because of the tanglement of the plant fibers.

We also found a paper from an art supplies store in Takapuna, however when we called them, they get the paper from America and were out of stock of it - they didn't know the paper very well.
