An experiment in knitting, using hexagonal-shaped units combined to form a larger hexagonal unit. Needs to be blocked to lie flat.
This is another idea in the realm of "substitution tiling." Take a shape like a hexagon, then subdivide it and subdivide it again. In this case, you take a leaf, then for the veins of the leaf substitute branches with leaves. This could be taken to another iteration, but I lost interest in actually knitting it.
