Beautiful colourway, very lovely. What did you start with as the base, was it a pre-made piece of fabric or roving or...? It looks so thin and light, I can't imagine felting that from bit poofy batts.
I took a piece of roving a bit longer than the length I wanted my scarf, then gently spread it out width-wise. I learned how to make this type of scarf from Tetyana Huffman. She calls it a Nori scarf.
