Ksenija Vojiasvljevic created this tangle, I am not sure where Ksenija is from but.... I love one stroke tangles and this one is fabulous.
I did the one below on gray paper and shaded it with graphite and white.
When I taught this in class on Tuesday it was a big hit. I love it with the "Fescu" and shading with graphite.
Step-outs are easy see below.
Here are a few more samples of DooLeeDo with some Tanglelations.
