A knot difficult to make

[struktor]

Toroidal two-sided fractal knot

I decided to transform the open knot into the torus.

You can see here the steps of this transformation:

At the end I cut and sewed the edges according to the rule:

Connection bight - bight.

In order not to cut and sew the edges
I developed a pattern to plait that knot.


Used tool

Unfortunately you can not remove a knot without destroying the pattern (and tool).

Result

Struktor
