My mother-in-law just got rid of the last of her knitting stash and in it, was 50 grams of white angora. I think it is sock yarn weight, but I'm not sure. I have attached two photos, one next to sock (fingering) yarn and the other with the ball in my hand. I wear a medium glove. It certainly isn't worsted weight, but I'm not sure about DK. I have some sport weight that is similar but this is still a tad smaller. Which do you think it is? I tried #2 bamboo needles as I use for socks sometimes and it was just too tight. I am getting about 5st (stockinette) per inch with size US6 needles. When I switch to US8, I am getting about 4.5/in stockinette, but it's a looser knit. I think the US6 is a good size if I turn this into a hat.
Also, does anyone know what I can make out of 50g of angora that is this weight?
