I had a couple of do-overs with these socks, but I'm so happy with how these came out it was worth it! I had to restart the intarsia section because the shark was puckered...then the foot was off so I had to rip back and start it over. But you know what? It's worth it when you're happy with the project in the end. And these were so much easier than the Shark Week socks I made! I used the yarns called for by the pattern, and I love the colors!
