I made the intentional decision to make fraternal twins, and I really like how they turned out, colorwise. I also like the sock pattern itself - I got a lot of questions about it on Instagram about what I thought of the OMG Heel (which stands for One-needle Mini Gusset). The short answer is yes - I ended up being happy with the heel it produced, and I would definitely it into other patterns.
The pattern itself (by Megan Williams of the Stockinette Zombies Podcast) is really well-written for both cuff-down and toe-up; the instructions are written for working on two needles via magic loop, but it's very easy to translate to DPNs for those of us who prefer that (ie, me). I will definitely be knitting the OMG Heel Sock pattern again: it's perfect for variegated, self-striping and hand-dyed yarns and it's easy enough to follow along when knitting on the bus/train/what have you.
