This step is optional, but I recommend trying it.  Lightly felting the scarf brings out some of the lovely fibers and compliments the beautiful texture of Seed Stitch. 

1. Block the scarf by gently stretching it along its width and length to even out the overall stitches.
2. Spray the scarf evenly with warm or hot water, or rinse it briefly under the tap (don't soak it, just get it damp). 
3. Rub the scarf, folding it against itself and rolling it around in your hands until the fibers are fuzzy and fluffy, but not matted.  Try not to twist, pull, or stress the fabric of the scarf during this process.  
   
4. When the scarf is felted to your liking, spread it out flat to dry.
