A barrel depends less on abundant wood grain than on narrow staves forming one gently bulging body, with hoops fitting around it. Draw an empty, open decorative barrel from slightly above its rim so the inner edge and a little inner wall are visible. This is a drawing exercise, not a manufacturable container design. Check first that both staves and hoops wrap around the same body, then add restrained aged wood colour and metal reflections rather than concealing structural errors with texture.

## Set proportions with a bulging silhouette

Create an approximately 1500×1700 px canvas with a pale warm-grey background. Connect the upper opening and lower base with a centreline. Bulge the middle sides slightly while narrowing the top and bottom, avoiding both a straight cylinder and an exaggerated ball. Draw a shallow ellipse for the rim and only a small base arc, facing consistently. Separate sketch, wood, hoops and interior, filling the silhouette with one brown first. Reduce the view and check that the axis passes through both centres. If one side bulges while the other stays straight, decide whether the asymmetry deliberately shows a turn; otherwise correct it. Grain cannot repair sides that fail to describe one body.

## Give the opening an outer and inner edge

Leave a narrow wooden band inside the outer rim ellipse and draw the smaller inner opening without letting its inner and outer edges exchange sides. Keep the rear half clearer while the front half hides the interior wall below. Fill the cavity with dark grey-brown, retaining a small lighter rear-wall area instead of making a featureless black hole. Hide body texture and check that the rim reads as a thick-edged opening rather than a black ellipse attached on top. Too much separation between the ellipses makes a thick bowl: narrow the band and check that stave ends join it naturally. Rim thickness should remain compatible with the apparent boards throughout the barrel.

## Turn stave joints around the surface

Begin with five to seven lengthwise joints across the front, leaving wider apparent intervals near the centre and narrower ones toward the sides. Bring the joints inward toward the rim and base, gently bowing their middle sections with the bulging body rather than drawing perfectly parallel straight lines. Use low-contrast dark brown initially, not deep black grooves in every joint. Hide the hoops and check that each stave continues from top to bottom. If a seam merges inexplicably with its neighbour midway, redistribute the stave widths in the sketch. These joints must describe the barrel rather than decorate it; fewer clear staves are preferable to dense lines that create false complexity.

## Wrap both hoop edges around the same body

Draw two narrow metal hoops, one high and one low, giving each an upper and lower edge that turn horizontally around the body. Let the front dip in a shallow arc and the sides turn out of view, rather than attaching a straight rectangular strip. Its width reads most clearly at the front and narrows at the sides without unexplained breaks. Begin in one blue-grey and check that the hoop covers the stave joints: those joints should stop behind its boundaries instead of crossing the metal face. If the middle floats off the wood while its ends cling tightly, correct the curve and shading before adding rivets or highlights.

## Place hoops without destroying the opening

Leave exposed wood between the upper hoop and rim so stave ends, rim and hoop each occupy a distinct area. Leave a little wood below the lower hoop as well, instead of encasing both ends in metal. Inspect both sides: the rear edge of the upper hoop must not slash diagonally out of the opening. If a joint is shown, add a short overlap on one visible front side rather than doubling the lines around the entire circumference. Trace the hoop in the sketch and imagine its hidden rear half returning to the visible front. Use that hidden route for checking only; drawing every rear edge on the front would turn the solid barrel into a transparent wireframe.

## Give wood and metal different value rhythms

Light the wood warmly from the upper left and darken the right with grey-brown, carrying the broad change continuously across several staves. Making every board half black and half white would suggest separate cylinders. Run restrained grain and a few curved short cracks lengthwise along the boards. Give the metal more concentrated pale reflection bands of varying width, keeping blue-grey in its dark portions instead of making the entire hoop pure white. Hide texture to check the volume, then restore it to compare materials. If wood looks metallic, reduce sharp glints. If hoops resemble cloth, concentrate a clearer reflection in one short area and keep selected edges crisp rather than equally hard everywhere.

## Check bottom support separately from the cavity

Add a short contact shadow below the base and extend the ground shadow toward the lower right. Keep it distinct from the cavity darkness so they do not become one black column through the body. Hide the interior first and check that the barrel stands securely. Then restore the cavity and hide the ground shadow to test the opening alone. These separate checks prevent a very dark shadow from disguising a floating base. If the rim resembles a crooked saucer, inspect ellipse and front/rear overlap instead of first adding more stave joints. If the base becomes pointed, widen its arc and reduce excessive side taper. Natural stave variation is acceptable, but the support footprint must agree with the stable pose of this decorative barrel.

## Keep stave colour variation within one volume

One or two staves may lean slightly redder or yellower, but compare those variations with the broad lighting first. A pale board in shadow should remain quieter than the main lit surface; each new board must not restart its own highlight system. Inspect a temporary greyscale version. If it contains abrupt vertical value stripes, reduce inter-board variation before restoring colour. Colour differences help distinguish staves without replacing their tapering joints. Even a distinctively coloured side stave must narrow in apparent width rather than becoming as wide as a front one merely to expose its grain.

## Test wrapping without texture

In a copy, remove grain, rivets and stains, retaining only opening, joints, two hoops and broad values. At normal size, identify which staves face front and where the hoops turn sideways; the thumbnail should still bulge. Sketch a deliberately horizontal false hoop for comparison, observing how it flattens the body, then confirm that the original avoids that error. After PNG export, inspect whether narrow side joints have collapsed into black patches or the upper hoop has sealed the opening. Save the editable original and record a structural change, such as fitting the lower hoop more closely to the right contour, rather than setting a goal of simply adding more grain.
