I am currently making socks with Knit Picks Essential. I have the Pine Green, Burgundy (more of a brick red), Purple Tweed, and a shade of denim blue called Dusk. I love all the colors.
It's the first time I use this yarn and my advice is to knit as tightly as you possibly can with this yarn as it is very stretchy. Am using #2 needles on this pair but will try #1 for the next pair.
I washed the first sock I made with KP and although not recommended I put it in the dryer and it dried w/o much shrinkage. The sock was knit with two strands of KP and makes a nice boot sock.
