Toast fine ink study
FinelinerChallenging

One soft pretzel viewed from slightly above with a coherent continuous dough loop crossing once in the middle. Practice clear contours and a few local shadows in fine ink.
Map the outer loop and central crossing.
Trace the dough through the crossing without breaking its thickness.
Refine the clear outer contour, add only the most useful interior details and place a few small local shadows. Leave most of the paper open.
A small thing to tryKeep the over-and-under crossing unambiguous.
