While I told you about the socks I designed for Knitcrate, I haven't showed you the pictures yet I took before I had to send my sample. And believe me, it was hard to let them go, because I so loved the yarn I used by Chasing Rabbits Fiber Co. Even though Fern comes with a nylon content, which I personally like for socks because it adds durability, the yarn is oh-so-soft and wonderful to work with. Not to mention its great stitch definition. I think the 'pairing' of the design with this great yarn worked just fine.
The next pictures shows the heel details of the Thunderbolt Socks. I've become really addicted to integrated heels lately. The fit is just as great as it is with socks with heel flap and gusset, so this heel version is perfect for me. And it is so versatile, so many possibilities to work it. For Thunderbolt I split it into four increase section which blend perfectly into the pattern.
