Laura Harms' Challenge #38 is all about paradox or as she playfully calls it, "Better than a Pair of Ducks."
I had to come out to play for this challenge! After all, this tangle is also called Rick's paradox. When I came up with this tangle, as far as I can remember, I hadn't seen it elsewhere. Since then we've learned that it is a quilting technique from at least as early as the 1950s.
We named this tangle "paradox" because by only using straight lines, you automatically create spiraling curves.
After I admired the many Zentangle paradox creations posted on Laura's blog, I considered different strings for my tile. Then I noticed the background design on her site . . .
. . . and chose that for my string or more precisely my paradox structure, since I created it in pen. I had already explored creating a two sided paradox. This would be a great opportunity to play with that form.
This was interestingly different because it uses mostly curved lines. The lines in the two-sided shape had to remain curved. However, in the four-sided shape I eased into straight lines after about four cycles.
I also broke one of my own "rules" and used a mechanical aid for my original circles. Everything after that was free hand. In this partially completed view you can see some of those initial lines.
I left a couple shapes undone to add interest and to show what shapes were used. I used a Sakura® Pigma® Micron 005 black pen throughout.
This experiment resulted in a beautiful tesselation. Notice how that single calla lily shape repeats itself and fits with itself to cover the surface.
Thanks for this challenge, Laura. I wonder if there is a "Pair of Ducks" swimming around this pair o' . . .
