Natural wools and fibres

I've been trying out different natural coloured wools with different natural fibres over the past few months. By 'natural' fibres, I mean plant based like bamboo, corn, soybean, hemp etc, though there have also been a few trials with leaves and stuff from the garden :)
Flax looks and feels just like dried plant material before felting, but after felting is a lot softer and shiny. This is a before and after felting picture of flax wet felted with natural brown merino tops:

Another combination I tried was Black Jacob tops and natural Soybean tops. As the felt was drying the soybean looked a gorgeous shiny golden colour:

One of my favourites lately was Oatmeal Bluefaced Leicester with Ingeo top, I covered the whole piece with Ingeo tops. This was another piece that really shined in the dim light as it was drying. Here's a half and half picture of drying and dry:

Humbug Jacob Tops is a blend of black and white Jacob fleece that gives a subtle stripey effect, I used strips of black and white bamboo with this. Black bamboo is very matt, and white bamboo is very shiny.

                                    

Do you have any favourite combinations of natural wools and natural fibres? It's really interesting seeing how a fibre can look very different depending on which wool it's used with.
