Before felting my Triffid Scarf I tied some foam balls into it with sewing cotton. I wanted a resist so that the areas where the foam balls were would not felt & after removing the balls the shape would remain. These would represent the fungus pods.
After felting I removed the foam balls. And, I forgot to add the hair conditioner to the red “tentacles” beforehand. When I realised this I stopped the machine a couple of times during the felting process and just separated the tentacles & gave them a twist.
