Mesmerising Merino Wool Top - M17These wool tops are 20. 7 micron Merino and come as a 100gram braid. Staple length approximately 10 11cm, which is a little longer than you mostly find for merino (commonly around 5 8cm). This is a non superwashed product and as such gentle handling is recommended (unless you are felting, then go your hardest!). This product is entirely Australian grown and manufactured. The farmer, the shearer, the scourer, the top maker are all located in Victoria.
