Trace four leg pairs to the cephalothorax; keep abdomen, pedipalps and antenna-like mistakes distinct.

A radiating spider silhouette can accidentally count pedipalps as ninth and tenth legs. Draw an invented generalised spider in an oblique upper view in Aquarell, separating cephalothorax, abdomen, four walking-leg pairs and shorter paired pedipalps. Establish exterior ownership without species-specific eye placement or venom assessment.

## Reserve room for eight legs

Use an approximately 1700×1500 px canvas with cephalothorax left-centre and abdomen right-centre, leaving room for leg bends. Connect two differentiated volumes through a narrow junction without a third detached head. Merge insect-like front segments or connect isolated stone-like masses. Omit a web so background lines cannot masquerade as legs. Invented proportions establish neither a measured species profile nor reproductive or feeding state.

## Place all four leg-pair roots on the cephalothorax

Mark four roots on each cephalothorax side, front to back, leaving abdomen margins leg-free. Draw eight initial paths and spread crowded visible roots. Abbreviate occluded far roots without relocating them onto the abdomen. Checking points are not measured segment coordinates. These four pairs are walking legs; later pedipalps are separate. Do not delete a pair merely to reduce clutter or substitute shadows for missing legs.

## Bend legs instead of radiating eight needles

Abbreviate each leg through two or three main directions from root outward and toward ground. Vary front/back angles and projected symmetry while keeping root-to-tip traceability. Add joints and taper to sun-ray needles; remove arbitrary small curls from rope-like legs. Avoid identical ball feet. Two or three drawing directions do not claim only that many anatomical leg segments; major bends simply make the pose readable.

## Place shorter pedipalps at the front

Add a shorter pedipalp pair near the mouth, separated visibly from front legs. They may bend but are neither forehead antennae nor part of the eight-leg count. Temporarily colour eight legs and two palps if ten legs appear. Avoid enlarged crab-like claws. Real male palps may differ, but this study makes no sex determination or unobserved genital detail. Abbreviate mouthparts to avoid confusing appendage ownership.

## Keep eyes and abdomen patterns schematic

Suggest an eye region with restrained dots rather than forcing a fixed arrangement. Let abdominal patterns follow volume without creating another region or wings. Reduce mouth-like dots and repair backpack-like abdomen continuity. Hairs are optional; body categories come first. General references do not specify this invented eye count, pattern or colour, which would need specimen evidence. The illustration establishes neither identification nor a basis for approaching a real spider.

## Keep occlusion and shadows from adding legs

Use pale ground, stronger near legs and softer far legs. Stop hidden lines at crossings. Keep contact shadows narrow and soft near visible tips, not another hard fringe from the abdomen. For nine legs inspect shadows/palps; for seven recover a real path lost in overlap. Adjust the invented view instead of exposing hidden segments. Unequal clarity is acceptable with explainable ownership; fading is not deletion, and elegant poses cannot justify unattached legs.

## Use separate eight-leg and two-palp lists

Hide hairs and shadows. List four left and four right walking legs separately from two front palps. Trace tip to root, verifying all eight on the cephalothorax and none on abdomen. Separate a shared line wrongly serving two legs, or repair an abdominal edge counted as a limb. Keep temporary numbers off final patterns. Recheck two body regions after texture: counts, attachments and body division are distinct checks.

## Reopen, recount and retrace roots

Save native work, hide labels/root points, export PNG and reopen. Read two body regions and leg spread small, then count eight roots enlarged plus two separate palps. Recover lost far legs through tone/crossing placement, never unattached filler lines. Reduce merged dark eye marks rather than enlarging the head. Revise, re-export and reopen editable structures/surfaces. Note a generalised invented spider, not a specimen. No eye-based identification, venom assessment, locomotion test or automatic appendage counter is implied.
