For this scarf, a 6" strip of plain black Polar Fleece, was embellished by needle felting yarn into the fleece.
Using a curved template and chalk to guide yarn placement, made this a fast and easy project. When the yarn was felted from both sides of the fleece the fleece lost all stretch.
Always experiment on scraps to see what the results will be with the fabric or fibers you are needle punching.
This example was made on a Janome Xpression Needle Felting Machine
