Binoculars fine ink study
FinelinerChallenging

One pair of slightly open scissors, two loop handles, one pivot and two continuous blades. Practice clear contours and a few local shadows in fine ink.
Set the central pivot and two blade directions.
Attach one handle loop to each blade through the pivot.
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 tryTrace each blade continuously into its own handle.
