Hamadox is the monotangle shown here. It is a combination of Paradox and Hamil. The step outs for this tangle are on the webpage of Diana Schrueur and can be found by clicking here. I had never tried this one before but I loved the flowing lines.
first stage - I drew a circle lightly with a pencil and when I drew the Hamadox I used the circle as a guide. I then added the rounding in the paradox section as Diana suggests.
The rounding has been filled in and then I filled in the outer areas for more drama. The tile was finished with a few details and some shading. (see above.)
Here is the sketchbook page I drew on as I practiced and then tried out a few tangleations.
