Merino is the best quality wool to felt with because it felts fast due the fibres being fine, it also comes in many colours. Merino is good to use when learning how to spin as it has an ideal staple length (length of fibres) of 4 – 5 inches. Merino fibres are very soft meaning the items you make feel nice next to the skin which is good for scarves, hats and jewellery.
