Most people think drawing a paper bag is easy. It’s just a brown rectangle, right? Wrong. If you approach it that way, you end up with something that looks more like a brick than a flexible object meant for holding apples and milk. Honestly, the grocery bag is one of the best exercises for any artist because it forces you to deal with physics. You have to understand how paper folds, how weight settles at the bottom, and how light hits those sharp, crinkly edges.
When you sit down to learn how to draw a grocery bag, you aren't just drawing an object. You’re drawing tension. You’re drawing the history of that bag—where it was gripped, how heavy the contents were, and how the "gusset" (that's the technical term for the foldable sides) behaves under pressure.
The Geometry of a Boring Brown Bag
Start with the ghost of a box. Don't press hard. Use a 2H pencil if you have one, or just barely touch the paper with a standard HB. You need a 3D rectangular prism, but here is the secret: it shouldn't be perfect. Real bags sag.
If the bag is empty, the top will likely be wider than the base. Why? Because the bottom is glued and reinforced. It’s rigid. The top is just open paper flapping in the wind. When you’re figuring out how to draw a grocery bag, sketch the base as a solid, flat rectangle in perspective, then let the vertical lines flare out slightly as they move upward.
Think about the "Y" shape at the sides. If you look at a standard grocery sack from the side, the fold creates a distinct Y-pattern. This is the gusset. It allows the bag to fold flat for storage but expand when filled. If you miss this detail, the bag looks fake. It looks like a solid block of wood. Draw that Y-fold with a slight inward curve. Paper isn't steel; it bows toward the center when it's empty.
Why Paper Folds are Harder Than Fabric
Fabric flows. Paper snaps. That is the fundamental difference you have to grasp. When fabric folds, you get soft "U" shapes. When paper folds, you get "V" shapes and "Z" shapes.
Look at the top edge of the bag. It’s rarely perfectly straight. It’s usually jagged from the factory cut or slightly crumpled from someone’s hands. Draw a zig-zag line. Vary the heights of those little peaks. This adds instant realism.
Shadows are the Secret Sauce
If you want the bag to pop off the page, you need to understand core shadows versus cast shadows. A grocery bag has many planes. You have the front face, the side faces, and the inner folds. Usually, one side will be in deep shadow.
But wait.
Inside the bag, it’s even darker. If the bag is open, the interior should be the darkest part of your drawing. Use a 4B or 6B pencil here. Don't be afraid of the dark. Most beginners make everything a medium gray, which results in a flat, boring image. Contrast is your best friend.
The Handles: Where Most People Mess Up
Are you drawing a bag with handles? Most modern paper bags have those flat, reinforced paper handles glued to the inside. They don't just stick out of the top. They have a point of attachment.
- Draw the attachment patches first. They are usually small rectangles.
- The handles themselves aren't perfect circles. They are loops of stiff paper.
- If the bag is being held, the handles will be taut.
- If the bag is sitting on a table, the handles might flop over.
Notice how the handles create their own tiny shadows on the surface of the bag. These "micro-shadows" are what convince the human eye that the object is real. Skip them, and the handles look like they’re floating in space.
Textures and the "Crinkle" Factor
Paper bags are tactile. They have a specific grain. To get this right, you don't need to draw every single wrinkle. In fact, if you draw too many lines, it looks like a spiderweb.
Focus on the major "stress points." These are usually at the corners and near the bottom. Use short, sharp, energetic lines to indicate where the paper has been bent. Then, use a blending stump or even your finger (though professionals might cringe at the oils from your skin) to soften the shadows around those lines.
Actually, use a tissue. It’s better than your finger. It keeps the "brown paper" look smooth while letting the sharp crinkles stay sharp.
Mistakes That Scream "Amateur"
One huge mistake is making the bottom of the bag perfectly flat on the ground. Unless that bag is filled with lead weights, the bottom edges will curl up slightly. There’s air under there.
Another error? Ignoring the "lip" of the bag. Most paper bags have a small fold at the top where the paper is doubled over for strength. It's a tiny detail, maybe only a couple of millimeters thick in real life, but in a drawing, it adds a layer of complexity that makes people think, "Wow, that person knows how to draw a grocery bag."
- Check your perspective. If we see the top opening, we shouldn't see the bottom as a flat line.
- Watch your line weight. Make the lines closer to the viewer thicker.
- Don't over-smudge. Keep some white space for highlights where the paper catches the light.
Rendering Different Bag Types
Not all bags are created equal. You have the classic brown Kraft paper bag, the plastic "thank you" bag, and the heavy-duty reusable canvas bag.
Plastic bags are a nightmare for beginners. They are translucent and shiny. You have to draw what’s inside the bag as much as the bag itself. You use a lot of "lost and found" edges where the line just disappears into a highlight.
Canvas bags are all about weight. They don't crinkle; they drape. The folds are heavy and rounded. If you're learning how to draw a grocery bag made of cloth, forget everything I said about V-shaped folds. You need soft gradients and thick, textured lines to show the weave of the fabric.
Light Direction Matters
Decide where your light is coming from before you even start. If the light is from the top-left, the bottom-right of the bag will be in heavy shadow. The "folds" facing the light will be almost white.

I’ve seen students try to shade a bag by just coloring the whole thing light brown. It doesn't work. You need highlights. Even though brown paper is matte, it still reflects light. Use a kneaded eraser to "pull" highlights out of your shading. Tap the eraser on the edges of the folds. It’ll lift the graphite and leave a crisp, bright line.
Real-World Practice: The Kitchen Table Method
Go to your kitchen. Grab a bag. Put a cereal box inside it.
Actually look at it. Notice how the corners of the cereal box push against the paper, creating new tension lines. This is called "form-finding." The object inside dictates the shape of the container. If you draw a lumpy bag but the viewer can't tell why it's lumpy, the drawing fails.
Try drawing the bag from a low angle. It makes the bag look monumental, like a skyscraper of groceries. Then try drawing it from directly above. It becomes a study in nested rectangles.
Final Touches and Context
A bag floating in white space looks like a clip-art icon. Put it on a surface. Draw a simple horizontal line for a table edge. Add a cast shadow. A cast shadow is the shadow the bag throws onto the table. It should be darkest right where the bag touches the ground. As it moves away from the bag, it should get lighter and fuzzier.
If you really want to go pro, add a little bit of branding. Don't draw a perfect logo. Draw a "suggested" logo. If the bag is wrinkled, the logo should follow those wrinkles. It should break and bend. This is an advanced move, but it pays off.
Actionable Next Steps
To truly master this, you need to move beyond theory. Grab a piece of charcoal or a soft lead pencil.
First, spend five minutes doing "gesture drawings" of the bag. Don't worry about detail. Just capture the "slouch" of the bag. Do ten of these from different angles.
Second, do a "blind contour" drawing. Look only at the bag, not your paper, and move your pencil slowly around the edges. It will look like a mess, but it trains your brain to see what is actually there, rather than what you think a bag looks like.
Finally, commit to a long-form study. Spend an hour on one bag. Focus entirely on the transitions between light and shadow. Look for the "halftones"—those middle grays that bridge the gap between a bright highlight and a dark fold.
Once you can draw a convincing grocery bag, you can draw almost anything. It’s all just planes, light, and tension. Grab a bag from under the sink and start. Focus on the gusset. Watch the shadows. Stop overthinking the "brownness" and start seeing the shapes. The more you draw everyday objects, the faster your "artist's eye" develops. Check your bag for any unique tears or staples; those little imperfections are what make your art feel like a real piece of the world.
