How to Draw With the Lasso Tool | Selection Art Technique

Drawing with the lasso tool means tracing a shape, closing the selection, then filling inside it to create solid blocks of color or texture.

You can learn how to draw with the lasso tool in about two minutes — the technique is simpler than it looks. Instead of pushing a brush around the canvas, you trace the outline of the shape you want, close the selection, and fill it with color, pattern, or texture. What you get is a clean, hand-drawn area that feels organic because it is hand-drawn, just defined by a selection border rather than a stroke.

What Does “Drawing With the Lasso” Actually Mean?

It means using the lasso tool to create a freeform selection border, then filling that selected area to produce a solid shape. You never draw a continuous line — you define the edges of a region and let the fill do the rest.

This is the core insight that separates lasso drawing from regular drawing. The lasso tool, as Adobe describes it, draws freeform segments of a selection border. Once that border is closed, anything inside it can be filled, painted, transformed, or moved independently. For artists, this makes it a fast way to block in rough shapes, add flat colors to a sketch, or isolate an area for editing without affecting the rest of the image.

In Photoshop, the lasso sits under the Marquee tool group. Select it, set a Feather value in the options bar if you want soft edges, and drag to trace your shape.

Drawing With the Lasso Tool in Photoshop — The Exact Settings to Use

The exact sequence is: select the Lasso tool, set Feather and Anti-alias in the options bar, drag to trace your shape, close the selection by releasing the mouse, then fill or paint inside it. Adobe’s official documentation confirms this freehand selection workflow.

Here’s the step-by-step:

  1. Select the Lasso tool from the toolbar (or press Shift+L to cycle through lasso variants).
  2. In the options bar at the top, enter a Feather value. A low Feather (0–2 px) keeps edges sharp; a higher Feather (10+ px) softens them for blended fills. Keep Anti-alias checked to prevent jagged edges.
  3. Drag across the canvas to draw your selection border freehand. The line follows your cursor like a pencil.
  4. To close the selection, return to the starting point and release the mouse. If you release elsewhere, Photoshop draws a straight line back to the start to close it automatically.
  5. Once selected, fill the area by pressing Shift+F5 (Fill), painting with a brush inside the selection, or applying a gradient, pattern, or adjustment layer that uses the selection as a mask.
  6. Press Ctrl/Cmd+D to deselect when you’re done.

To switch to straight-edged segments mid-trace, hold Alt (Windows) or Option (macOS) and click where each segment should start and end. Release the modifier to return to freehand mode. The selection mode controls in the options bar — Add to selection, Subtract from selection, and Intersect with selection — let you build complex shapes by combining multiple passes. Adobe’s lasso tool documentation covers every option in detail.

Lasso Tool Variants and When to Use Them

Photoshop gives you three lasso variants, and the best one for drawing depends on the shape you’re after — freehand for organic curves, polygonal for straight edges, and magnetic for tracing photo edges.

Feature What It Does Best For
Freehand Lasso Drag to trace any path freely Quick organic shapes, loose blocking
Polygonal Lasso Click to set straight-edge endpoints Angular forms, geometric blocks
Magnetic Lasso Snaps to high-contrast edges automatically Cutouts from photos, tracing visible boundaries
Feather setting Softens the selection border by a set pixel radius Blended fills, soft-edged shapes
Anti-alias Smooths the jagged pixel edges of the selection Clean fills on any shape size
Add to selection Combines a new lasso pass with the existing selection Building up complex composite shapes
Subtract from selection Removes a traced area from the existing selection Carving out negative space or holes
Intersect with selection Keeps only the overlapping area of two selections Precise overlays and intersecting geometry

For the Polygonal Lasso, hold Shift while clicking to constrain segments to 45-degree increments — helpful for isometric or angled geometry. For the Magnetic Lasso, click at the edge of the area you want to trace, then drag along the edge; the tool snaps to contrast boundaries and places fastening points you can adjust.

What Shortcuts Speed Up Lasso Drawing?

Four keyboard shortcuts handle nearly every lasso drawing task: Shift+L to switch variants, Shift to add to a selection, Alt/Option to subtract, and Ctrl/Cmd+D to deselect. These keep your hands on the keyboard instead of reaching for the options bar.

Shortcut Action Platform Notes
Shift+L Cycle through lasso variants All
Shift (held) Add to existing selection All
Alt (held) Subtract from existing selection Windows
Option (held) Subtract from existing selection macOS
Ctrl+D Deselect Windows
Cmd+D Deselect macOS
Ctrl+Z Undo last action Windows
Cmd+Z Undo last action macOS
V Switch to Move tool All

The Move tool (V) is useful after a lasso selection — it lets you reposition the selected area or drag it to another document. For quick undo of a bad lasso trace, Ctrl/Cmd+Z is faster than redrawing.

Using the Lasso in FlipaClip and Clip Studio Paint

The same trace-and-fill logic works in other drawing apps, though the controls differ. FlipaClip uses the lasso for moving and transforming drawings, while Clip Studio pairs it with a Reference Layer for clean color fills.

In FlipaClip, the lasso tool selects a drawing by tracing around it. A dotted-line box appears around the selection, and a double-tap can auto-select the object on the current frame. Once selected, you can move, copy, paste, resize, rotate, or flip the drawing — useful for frame-by-frame animation cleanup.

In Clip Studio Paint, the Magnetic Lasso snaps to edges much like Photoshop’s version, and you can pair it with a Reference Layer — a layer that stores the line art while you fill flat colors on a separate layer beneath it. This prevents the fill from bleeding past the lines.

Common Mistakes and How to Fix Them

Three mistakes cause most lasso-drawing frustration — unclosed selections, over-feathering, and using the Magnetic Lasso on low-contrast edges.

  • Unclosed selection. If the selection border doesn’t return to its starting point, the fill may behave unpredictably. Fix it by completing the loop or using the Polygonal Lasso for shapes where you can control every endpoint.
  • Feather too high. A high Feather value blurs the edge of the fill so much that it loses definition. Keep Feather at 0–2 px for sharp shapes, and only raise it when you specifically want a soft transition.
  • Magnetic Lasso on low contrast. The Magnetic Lasso needs a clear edge to snap to. On a blurry photo or a gradient, it wanders. Switch to the Freehand or Polygonal Lasso instead, or manually correct the fastening points.

In FlipaClip, careless resizing or rotating after a lasso selection can distort the shape. Use undo (Ctrl/Cmd+Z) right away if the result looks wrong, then re-select more carefully.

Quick Lasso Drawing Workflow Checklist

Follow this order for consistent results every time.

  1. Choose your lasso variant — Freehand for curves, Polygonal for angles, Magnetic for traced edges.
  2. Set Feather (0–2 px default) and confirm Anti-alias is on.
  3. Trace the shape, closing the selection by returning to the start.
  4. Fill, paint, or apply a texture inside the selection.
  5. Add or subtract from the selection to refine the shape as needed.
  6. Deselect (Ctrl/Cmd+D) when finished.

This sequence works across Photoshop, Clip Studio, and most lasso-equipped apps. The only difference is where the lasso tool lives in the toolbar — look for the dotted-line icon near the top.
