Do you think you saw the published one a while back, and remembered the design (but not that you'd seen it before) when you went to make yours, or is it a complete coincidence?
It's possible that I've seen a picture of it, but even then it's been in my subconscious. I had never seen the pattern before, the "original" was self published in a blog.
And this one was funny because I just sat on my sofa with needles and yarn and it sort of just happend to become a hat with a twist. I thought it looked cool and different so I designed the mittens to go with it...
And just for the record, I still think it looks good
And my version has a few "things" that makes it special, it's that on my hat, every other cable ends with a loop, and the decreases are hidden in the loops.
This blue on is the one that I knitted first. You can see the loops.
And on the mittens the thumb "comes out" of a cable twist. So if you really think about it, they are not that similar after all
