For the red toadstool caps I managed to find some 20g skeins of Red Anchor Tapisserie wool that had been reduced.
Due to the impulsive "have to make it Now!" aspect of my personality I bought it and hoped for the best.
The Tapisserie wool felted really quickly. I made a mental note to scoop up any reduced skeins on my next visit for felting.
Thought I'd post this pic of me tinkering with the mushrooms in the forest.
I'm still knitting and felting so there may be more mushrooms to follow.....
