Zen Tangles and Stitching

Besides the Knoxville FreeStyle EGA group, I am a member of the Atlanta EGA group, Stitching With A Twist.  This group is working on a project that will require our developing zen tangles that we stitch-- "tangling," it is called.  My problem is that I can't draw a tangle and then stitch it.  I think in reverse.  To me, it is easier to think of stitches that will work in a zen tangle and then draw the tangle based on those stitches rather than the other way around.

This is the beginning of my little sampler of possible tangling stitches (somehow, calling a stitch a "tangling stitch" sends the wrong message).  It is stitched mostly in a single strand of cotton floss, and, at lower center, with some DMC matt cotton the weight of a wool tapestry yarn:

There as many stitches on the "won't work" Doodle Cloth as this Sample!  A nice occupation for a snowy February day.
