Most spider drawings are a circle with eight sticks. This one is an orb-weaver, the fat garden spider that sits in the middle of a big wheel web, and it comes out with hairy shaded legs, a patterned abdomen and a shadow that makes it look like it is standing on the paper. It takes about fifteen minutes.
The walkthrough follows Art Hub Plus on YouTube, filmed straight down over the page so every stroke is visible. The sketch is three shapes and eight lines. Everything that makes it look real comes after: one tan marker, a black pencil, a blender, a white pencil and a light gray for the shadow.
What you need
A coloured pencil for the sketch (orange in the video, any colour works), a tan alcohol marker, black and white coloured pencils, a colourless blender marker and a light gray marker. Marker paper stops the colour bleeding through. If you only own a pencil, do the whole thing in graphite. The steps are the same, you shade instead of colouring.
Why it looks real
Three things. The legs are dark at the tips and joints and light in between, which is how a real spider's legs are marked. The abdomen has a pattern of tan shapes on a dark ground instead of one flat colour. And there is a shadow. Skip the shadow and it is a drawing of a spider. Add it and it is a spider on your desk.
Where it goes wrong
The back legs run off the page. The abdomen went in too big. Draw the oval lower and smaller than feels right, or accept shorter back legs the way the video does.
The shading looks scratchy. That is what the blender is for. One pass melts the pencil strokes into the marker.
The pattern disappears. The shapes need to stay tan. Shade between them, not over them.
More Halloween drawing
A spider pairs with a bat, which is one black silhouette, and a shaded ghost that uses the same black, blender and white layering as this one. A jack-o'-lantern rounds out the set. For the fundamentals underneath all of these, start with how to draw.
