Here is the wood heart I picked up at the bank - I painted the sides not knowing what I'd be doing as far as finishing them.
For the background for the heart I decided I wanted to felt some pink wool. I started out with wet felting some wool I had dyed but wasn't happy with that so I then moved on to knitting a blank which I then felted in the washing machine. It turned out great although it was touch and go on if it was big enough - just made it with a quarter inch to spare on the sides.
These are the flat pieces in black and natural I'm needlefelting to make the sheep's body. In needlefelting I use a needle with barbs that as it gets punched through the wool it felts it together.
Here I'm starting to felt the sheep body to the pink felted background. I cut out the shapes from the flat pieces of natural and black felt that I made.
Here is the piece after I've needlefelted the stems on using green wool. I've started felting the leaves on - I made them the same way I made the body felting 2 colors of green into a flat piece and then cutting the leaves out of it.
