Can I Knit Bark?

I find myself drawn back to the traditional skills I learnt as a child.  The question is how well will knitted bark samples work?

This one features knitted bobbles before the whole piece was felted and needle felting to (unsuccessfully) add carded wool onto the surface.

This time I tied resists into the knit before felting (Shibori) – which I really do like – and then added hand embroidery to the surface.

Finally an attempt at knitting some of the bark texture – possibly some potential in this but I’m keen to explore the Shibori felting method as this seems to give the strongest samples so far.
