I just started my first mystery KAL sock. I'm pretty excited about it. It's designed by Yarnissima. She designed Firestarter. The mystery sock is called Kiila. I'm using Knit Picks Essential Kettle Dyed in Gold. I'm working the socks two at a time while I wait for the next part. The KAL started May 1st and the first part was the foot (toe-up socks). She just released the gusset part today. Can't wait to start the gusset, but I'm trying to finish the second sock's foot before I start that. This is knitting up pretty fast and so far loving it. I'll try and keep you posted with the progress of the socks.
