For the octopus, I used this pattern by Hansi Singh via Ravelry. While the pattern calls for worsted weight yarn, I opted for Kambgarn sport / 5 ply yarn in Rosebloom and Glacier Green, which I had bought in Iceland (read about my trip here!) with size US2 double pointed needles. This of course made the octopus smaller and more delicate, which I liked. You can see more pictures of the octopus, including execution pictures, here.
For the tea cosy itself, I used this pattern by the blog Cast On Cast Off. It is a modified ribbed pattern, which I thought kind of mimicked an ocean rock. I knit it with Cascade 220 Heathers in Dark Charcoal, color no. 4002, which has a nice color variation going on, making it look more earthy, or rock-like in this case.
I then embellished the tea cosy with a seaweed design made using tambour crochet. You can learn how to tambour crochet here. I used a left over green yarn that I had gotten second-hand, so I don't know its specs.
While this project took me a while, it was a lot of fun to knit. I like knitting amigurumi (see my pug, bulldog, tea cup), and the tea cosy itself was quick and easy. Tea cosies are great because you are encouraged to be creative. I'm currently brainstorming ideas for my next tea cosy, so let me know if you have a fun idea!
