This one of the ways I make a felted picture.
I cut all the houses out of prefelt which I had previously made.I then needle felted the doors and windows onto the houses.
I laid out three layers of white wool as a base.White is best as it acts as a light base darker wools can migrate through.I then started to lay out the road.Then the sky with loose fibres then the hills in prefelt.
The houses and trees were next after some gentle rubbing to keep things in place it was rolled until felted
