Did this one a few weeks ago. It’s a square knot. I was thinking of if I would share any of these, but saw you’d done a tutorial on using the Draw Curves tool… well, I started this off with that tool.
One of the things I like doing with these is experimenting with the textures to get different looks. After converting this to a mesh, I added a seam and unwrapped it. In the texture, I added a brick texture into a color ramp. I set the width and height on the brick texture to the same with no overlap to get the tiling pattern. Then using the bias, I was able to narrow it down to the colors between .2 and .8 for the color stops to get the segments I needed for the scrambled Rubik’s Cube pattern.
The background is a magic texture with a color ramp tweaked to make it look like a fabric pattern.
