Beginner Course · Lesson 2 of 3

Meet the Stitch Editor

The most important lesson in the course. Get comfortable inside the editor, understand the layers panel, and learn the three stitch types that every embroidery design is built from — fill, satin, and running.

~6 minutes Core concepts Free to try

In Lesson 1 we uploaded our daisy and the AI processed it into color layers. Now we'll step inside the Stitch Editor and understand what you're actually looking at — the layout, the panels, and the three stitch types that are the foundation of machine embroidery.

What this lesson covers

  1. 1 The editor layout and where things live
  2. 2 The Stitch Colors (layers) panel
  3. 3 Fill stitch — patterns, angle, spacing, underlay
  4. 4 Satin stitch — columns, rails, and the width rule
  5. 5 Running stitch — single-line detail

The editor layout

Canvas · Toolbar · Stitch Colors · Export

Here's the Stitch Editor. Up top you have the quick Export button — that's how you get your finished file. The large canvas in the middle shows your design. Down the right is the Stitch Colors panel — your layers.

Click through the layers on the right and the toolbar updates with all the tools you can use to edit that layer. We'll go over each tool in detail in Lesson 3.

The Stitch Colors panel

Each row is a thread color

The Stitch Colors panel is worth spending a moment on. Each row is a separate thread color — the same way your machine stitches one color at a time. Click any row to select that layer and start editing it.

AI Optimized badge
Notice the AI Optimized badge at the top of the panel. It means the AI has already analyzed your design and pre-set a recommended stitch type for every single layer — so you're starting from a smart first pass, not a blank slate.

The three stitch types

Fill · Satin · Running

There are three stitch types, and understanding when to use each one is the most important thing you'll learn in this whole course. Most designs use a mix of all three — and the AI has already made a first pass at assigning them for you.

Fill

Rows of stitches covering a large solid area — petals, centers, backgrounds.

Satin

Smooth, glossy columns on narrow shapes and outlines.

Running

A single clean line for fine details, stems, and outlines.

F

Fill stitch

For solid areas — petals, centers, leaves

Fill stitch covers solid areas. Think of it like mowing a lawn — the machine goes back and forth across the shape in parallel rows until every part of it is covered. It's what you'll use for any large solid region.

Four pattern options:

1

Auto Fill

The one you'll use most. Picks the best angle automatically and gives clean, even rows.

2

Contour

Follows the outline of the shape, stitching in concentric rings — great for circular or organic designs.

3

Circular

Spirals from the center outward.

4

Meander

A random, flowing path that covers the area without rigid rows.

Beyond the pattern, there are three settings worth knowing:

Fill settings
Angle
0° · 45° · 90°
Direction the rows run
Row spacing
Density
Closer = heavier; wider = lighter & faster
Underlay
Base layer
Stabilizes fabric, prevents puckering
Try it in the editor
Click a petal layer, then click Stitch. Fill is selected and the canvas fills with the pattern. Switch the pattern dropdown between Auto Fill, Contour, and Meander to see the difference live.

Satin stitch

For narrow shapes and outlines — that smooth, glossy look

Satin stitch creates that smooth, glossy look by stitching back and forth across a narrow column — left edge to right edge, over and over. The result is dense, silky coverage with a sheen that catches the light.

The width rule
Satin works best on narrow strips — typically under about 6mm wide. On a wider shape the stitches become too long and start to snag. That's why you'll often use the Split tool first to divide a wide shape into narrower sections before applying satin (covered in Lesson 3).

Satin rails — 3 ways to set them

Rails are the two edges that tell satin which way to run across your shape. There are three ways to define them:

1

Split into Satin Columns

The fastest. Click two opposite edges of the shape — the app auto-assigns the rails and fills the satin for you. Keep the shape narrow; split wider shapes first.

2

Select Satin Columns

For designs that already have two separate closed paths, one inside the other. Click the outer path as Rail 1, the inner path as Rail 2 — the app fills the ring between them. Perfect for rings and any defined inner/outer edge.

3

Draw Edges

Full control. Pen-draw Rail 1 on one side and Rail 2 on the other, directly on the canvas. Best for unusual shapes where the other methods don't quite nail the boundaries.

Guide rungs
Once the rails are set, green guide rungs appear between them to steer stitch direction. On a straight shape the defaults work fine. On a curve, click between the rails to add more rungs — more rungs means the stitches follow the curve more cleanly.
R

Running stitch

For fine details, stems, and delicate lines

Running stitch is the simplest of the three — individual stitches placed one after another along a path. No width, just a clean trail following the shape. It's great for fine details, delicate stems, and anything that should look lightweight rather than solid.

Need a thicker line?
Increase the Bean Repeats setting. That tells the machine to retrace the same path two or three times, building up weight without switching stitch types.

Frequently asked questions

What are the three embroidery stitch types?
Fill, satin, and running. Fill covers large solid areas with rows of stitches. Satin creates smooth glossy columns on narrow shapes and outlines. Running stitch is a single clean line for fine details and stems.
When should I use satin stitch instead of fill?
Use satin on narrow shapes and outlines — typically under about 6mm wide — for a smooth, raised, glossy finish. Use fill for wide solid areas. For a wide shape, split it into narrower sections first, then apply satin to each piece.
What are satin rails and guide rungs?
Rails are the two edges that tell satin which direction to run across a shape. Set them three ways: Split into Satin Columns (click two opposite edges), Select Satin Columns (pick an outer and inner path), or Draw Edges (pen-draw both rails). Guide rungs are the green lines between the rails that steer stitch direction — add more on curves for cleaner results.
What do the four fill patterns do?
Auto Fill picks the best angle automatically (use this most). Contour follows the outline in concentric rings. Circular spirals from the center out. Meander covers the area with a random flowing path instead of rigid rows.
What is underlay?
Underlay is a thin base layer the machine stitches first, before the main fill. It stabilizes the fabric and prevents puckering — especially important on stretchy materials.
