Use a single curled shaving to study the two sides of a thin ribbon, changing apparent width, grain direction and a continuous painted edge.

A curled pencil shaving is neither a solid spiral shell nor a thick line. It is a wooden strip with width, two sides and a thin edge that partly overlaps itself as it curls. Draw an invented shaving with a red painted edge; no actual pencil-sharpening operation is required. Trace its continuous surface like a paper ribbon before adding fibres and small chips. Layers in Aquarell help separate sketch and details, but they do not automatically determine which side faces the viewer; every turn must be explained manually.

## Begin with a strip of explicit width

On an approximately 1600×1600 px canvas with a pale grey-cream background, sketch a loosely curled centre route like a slightly oblique open loop, not many tightly packed coils. Draw boundaries on either side to establish a narrow but readable strip, extending its end toward the lower right. Separate sketch, wood base, coloured edge and fibres. Do not keep both boundaries mechanically parallel at constant apparent spacing; the visible width narrows where the strip turns edge-on. Fill it with one colour first and confirm it reads as a ribbon rather than a tube. If the middle resembles round rope, expose a clear surface between its two distinct edges.

## Leave room for both ends and the opening

Mark the near and far ends, keeping them from lying exactly on top of one another. The near end may show a slightly wider oblique cut; the far end can tuck into the curl but should leave a traceable cue. Keep the central opening clear enough to show background rather than filling it into a wooden disc. Inspect this negative space: its narrowing and any overlap by the front strip must agree with the apparent ribbon width. If the inner curl begins to resemble a snail shell, reduce the coil count, separate the ends and remove the continuously enclosed pointed core. The subject is one thin shaving curling up, not a new solid object with an internal nucleus.

## Identify the two faces before shading

Use pale honey colour for the lighter outward face and a slightly darker grey-brown for the inward face. Mark the short turning region in the sketch first: one boundary turns behind while the other comes forward, rather than the colour switching abruptly without a transition. Keep the light from the upper left; face colours aid identification but do not make the reverse permanently the darkest area. Hide the outlines and check that the value shapes still join into one strip. If they resemble two separate shavings assembled together, reconnect the turning boundaries before adjusting shading. Avoid white edges everywhere; only selected edges facing the light need them.

## Continue the red paint along one long edge

Place a narrow red band on one chosen long edge, tracing it from the near end through the curl to the far end. It can appear slightly wider facing the viewer, narrower edge-on and interrupted where the front portion hides it, but the point where it reappears must connect. Do not jump midway to the opposite edge and apparently exchange the strip’s sides. Hide the grain and slowly follow the red edge against the contour. If an overlap is uncertain, sketch its hidden route as a dashed guide, then omit that guide from the finished image. The red edge belongs against the wood surface; it is not a separate cord floating around the outside.

## Run grain along the strip, not the canvas

Draw fibres in lines slightly darker than the base, following the strip length. Bend them together around turns and compress them into shorter, closer marks on edge-on portions. Horizontal grain across the entire canvas would flatten the curl. Begin with only three or four main fibres, checking that they turn around the surface before adding a few broken fine marks. Keep texture inside the contour and out of the central background, hiding it beneath overlapping front sections. If dense marks resemble hair, reduce their count and contrast rather than blurring them into a dirty patch. Grain is a surface cue and should remain quieter than the red edge and opening.

## Keep edges and breaks thin

Add a short pale thin edge at the near end and perhaps two or three small pointed chips at the break, without spacing notches evenly around the whole strip like a gear. Strengthen an interior dark line only at a genuine turn or overlap, keeping other boundaries lighter. Check the silhouette in one colour: even a broad near end must not abruptly thicken into a board. A narrow occlusion shadow beneath the front strip can show depth; identical black bands on both sides cannot. Check that the red painted edge remains thinner than the shaving itself. If it looks like rigid plastic trim, reduce its width and bright-white highlights to retain one lightweight wooden material.

## Use a contact shadow to locate the shaving

Choose a short part of the near end to touch the tabletop while the curl lifts slightly away from the background. Place a short dark shadow beneath the contact, with softer, slightly more offset shadow under lifted sections, keeping one light direction. An equally wide shadow around the entire contour would resemble a flat sticker. Hide the grain and judge where the object rests and where it rises using only the form and shadow. If the loop stands unsupported in midair, lower its height or establish a plausible contact section. Shadow explains this ribbon’s pose without specifying physical height or claiming an automatic depth-of-field effect from hand-painted softness.

## Check continuity without texture

Keep a copy with grain and coloured details hidden, using two greys to check width, overlap and the opening from near end to far end. In another sketch, deliberately join the red edge to the opposite boundary to see the resulting error, then confirm that the original contains no similar side-switch. Change this one relationship only, without also replacing the lighting and pose. If the ribbon remains unclear, simplify it to half a turn and rebuild the turning region rather than packing in texture. At normal size, identify where the front strip covers the rear; zoom only to refine edges. A few fibres can establish material on a sound structure, while abundant grain cannot repair a discontinuous ribbon.

## Inspect thin edges and the opening after export

Save the layered original and export a PNG at its intended display size. Inspect whether reduced dark edges have sealed the opening, whether the red edge forms an unintended complete circle, and whether the broken near end still looks thin. If the red dominates, first lower its saturation or visible width rather than darkening all the wood. Keep a greyscale structural preview and a finished version. A future study can curl the strip another way while retaining the same continuous-edge rule. Record a definite location, such as grain crossing the upper inner boundary, which is more actionable than saying it does not yet look wooden.
