I gave it a nice long bath in hair conditioner to make it softer. The Fabel sock yarn definitely needed it to bloom, it felt kinda stringy.
Sadly, after soaking and blocking, the Fabel yarn is still scratchy. I'll have to wear a cotton t-shirt underneath. Yes, I should have known it was a bad yarn choice but I liked the colours too much to be sensible... Oh well, live and learn.
I have to admit that I'm a lot like the "Princess and the pea", I can feel everything! If it isn't really soft, I can't wear it next to my skin. Since I value comfort above all else, I have many form fitting t-shirts I wear under stuff, so it's all good. ;-)
