This is Wool Color sock knitting yarn from Regia. This is shade #1933 which is called Denim Schwarz and is a mix of grey shades.Nice colors for men.
The yarn is 75% wool and 25% polyamid. It is machine washable and does not felt and is color fast.
It knits on 2.5mm / 3mm needles at 30 stitches over 42 rows for a 4" square.Each ball is 230 yards in length and you will need 2 balls for one adult pair of socks.
I have sock needles available in a variety of sizes.
