The Sierpinski Carpet is a type of fractal — meaning, in simple terms, that it is a shape made up of smaller copies of itself, which are in turn made up of smaller copies, and so on ad infinitum. Fractals can be simplified by only extending them to a certain iteration — and some simplified fractals can be charted for knitting. This fractal is created by starting with a square, then dividing it in 9ths (with a 3×3 grid) and removing the center square. Further iterations are created by subdividing the resulting squares, etc. “L5” refers to the fifth “level” or iteration of this fractal.
The first Sierpinski blanket was made to be a baby blanket partially because I (and my sample knitter) didn’t have time to do what I really wanted to do. Finally, I had the time to realize my original plan, and the new version is a full 45″ throw blanket.
This pattern is currently available only in the 2018 revision of Extreme Double-knitting.
