does this pattern remind anyone else of those tiktok videos that screenshot something random like an emoji and then change the saturation and stuff of the screenshot until it's the Poland flag with the music I love Poland by Hazel in the background?
Using the straight edges technique means changing the strings on the left edge to bf knots and on the right edge to fb knots. In this pattern you don't need to add an extra string, because you can just change the knots at the edges without affecting the rest of the pattern because they're all between two strings of the same colour.
I don't know other techniques that have similar effects, but maybe someone else knows 😄
