For sample two, I put down a thin layer of brown roving. On top of it I added pieces of fabric, sari ribbon, and wool yarn. I then added a second layer of roving perpendicular to the first alternating green and orange. This roving layer covered up all of the fabric and ribbon so I wasn't sure how it would look once it was felted but I was really pleased.
Sample two felted. Even though all of the fabric and ribbon was covered with the second layer of roving, this piece yielded some great texture and I love the effect. This one shrunk the most and came out about 6"x6".
