This is the one I've struggled with the most. In order of bending line like I wanted, I had to create a pattern brush in illustrator, but it couldn't be photo brush like I've done before, because they always make this one pixel thin brake between segments due to the clipping mask. At first, I thought, that I have to imitate somehow rope texture with Illustrator effects. I had tried many things, filters, filters with gradients, but nothing seemed to be realistic enough, and finally I was left with one way I didn't tried yet - traycing a photo to a vector, and then, when I appropriately prepared photo, trayced it, and made into a pattern brush it worked, barely, cause its quite heavy anchors and paths number.
