Stitch order and pathing: sequencing a design to cut trims and control distortion

Sequencing is the part of digitizing that the preview hides best. On screen, a finished design looks the same whatever order it was stitched in. On fabric, order decides whether outlines land on their fills, whether the back is full of trims, and whether a design takes twelve minutes or twenty. This page covers how to plan the path; for the registration consequences in depth, see registration.

Layering back to front

Embroidery is built in layers like a painting. The sky goes down before the mountain, the mountain before the tree, the tree before its outline. Each later object covers the edges of earlier ones, which hides small gaps and lets you skip stitching areas that will be covered.

Two practical points:

• Do not stitch what will be hidden. If a fill sits entirely under another fill, cut the hidden part out of the lower object and leave only a small overlap (around 0.3 to 0.5 mm) at the seam. Stacked full fills make stiff, heavy patches that pucker and stress needles.
• Outlines and details go last in their area. An outline stitched before the fill it borders will be pushed out of place or partly covered by the fill.

Sometimes correct layering requires going back to a color. A dark detail sits on a light fill, then another light shape overlaps the detail. That adds a color change, and it is worth it when the layering is visible.

Center-out sequencing to manage distortion

Every stitch pushes fabric along its direction and pulls it across. If the design starts on the left and works right, all the push accumulates toward the right, and by the far side the fabric has crept. Outlines there miss their fills while outlines near the start look perfect.

Starting near the center and working outward spreads that movement in both directions, and the free edges of the stitching area can absorb it. Fabric is pushed toward the hoop, not trapped between two finished areas where it bubbles into a pucker.

• Large designs and jacket backs: start with central elements and work out in rings or quadrants.
• Lettering arcs: start from the center letter and alternate outward, particularly on caps.
• Caps: center outward and from the brim upward is the standard approach, because the cap front is curved and stiff and fabric trapped in the middle cannot escape. See caps and hats.

Center-out sequencing sometimes means more travel or an extra color change. On a flat, stable woven with a small design, the benefit is minor. On knits, caps and large designs, it is often the difference between a flat and a puckered result.

Entry and exit points

Every object has an entry point (where it starts) and an exit point (where it ends). The machine has to get from one object's exit to the next object's entry somehow: with a travel run stitched on the fabric, a jump stitch (the needle stops penetrating while the hoop moves), or a trim followed by a jump.

Good pathing places each exit as close as possible to the next entry. Most digitizing programs let you set these manually, and many have an automatic option (often called auto-branching or closest-join) that does it for groups of objects. Some practical guidance:

• Satin columns can usually be stitched from either end. Choosing the end nearest the next object can eliminate a jump.
• Fills can enter and exit at almost any point on their edge. Set the exit on the side facing the next object.
• Lettering usually enters each letter at the left and exits at the right, so the next letter starts close by.
• Avoid entering on a visible edge that must be crisp, such as a sharp point. The lock stitches at entry can make a small bump.

Travel runs: hidden connections instead of trims

A travel run is a running stitch, usually around 2 to 3 mm long per stitch, that moves the needle from one object to the next while stitching. It replaces a trim and a jump with stitches that will be covered later.

The rule is simple: a travel run is only acceptable where a later object of a different color, or later stitching of the same color, will cover it completely. A travel run on bare fabric is a visible mistake. Good places to route travel include:

• Under the fill or satin that stitches next.
• Along the edge of a shape where its outline will cover it.
• Through the inside of the current fill before its top stitching goes down (many programs do this automatically for the fill's own underlay).

Watch light colors: a dark travel run under a light satin can show through, especially with thin or light thread. Route dark travel under dark objects where possible.

Lock stitches and tie-ins

A lock stitch (tie-in at the start, tie-off at the end) is a group of very short stitches, often around three to four stitches of about 1 mm or less, sewn in a tight pattern so the thread grips the fabric. Without them, a trimmed thread end can work loose and the first or last stitches of an object pull out.

• Tie-off before every trim. Most software adds this automatically when you set a trim.
• Tie-in at the start of each object after a trim or color change. On some machines the first few stitches are also slowed to help the thread catch.
• Hide them. Place tie-ins and tie-offs where later stitching covers them. On a satin edge or a small detail, a lock stitch can show as a lump.
• No lock between connected objects. When a travel run continues straight into the next object, a lock is unnecessary.

Trims, jumps and color changes on single-needle vs multi-needle machines

On many home machines with an automatic thread cutter, there is a setting for jump stitch trimming, and some let you set a minimum jump length below which the machine does not trim. Check your manual for whether yours trims jumps automatically and how the length threshold is set. Formats differ too: DST has no dedicated trim command, so trims are usually encoded as a short series of jumps that the machine reads as a trim, while some home formats store trims more directly. Converters usually handle this, but a converted file that suddenly has untrimmed jumps everywhere is a sign the trim commands were not translated. The converting file formats page covers this.

For more on machine differences, see single vs multi-needle machines.

Minimizing trims and jumps: a working order

1. Group by color within each area. Stitch all same-color objects in one region before moving on, rather than visiting the whole design per color.
2. Order objects so each exit faces the next entry. Use the program's closest-join or branching tool for groups of small objects such as dots or lettering.
3. Replace trims with hidden travel wherever a later object will cover the path.
4. Leave short jumps if they will be covered or are easily clipped, and trim long ones. Long untrimmed jumps catch on the presser foot and can pull stitches out.
5. Check the stitch simulator. Watch the path at slow speed: every visible line between objects is either a travel run that needs covering or a trim you may not need.

Sequencing mistakes that show on the fabric

Outline lands beside its fill

The outline stitched long after the fill, after other objects moved the fabric. Bring it closer in the sequence. See outlines not lining up.

Pucker trapped between two finished areas

Stitching worked inward from two sides. Resequence center-out.

Visible lines of thread between shapes

Travel runs on bare fabric. Reroute under later objects or use a trim.

Stitches unravel at the start of objects

Missing tie-in after a trim. Add lock stitches.

Bumps at corners of satins

Lock stitches on a visible edge. Move entry and exit points under later stitching.

Stiff, heavy areas

Full layers stacked under other fills. Remove hidden stitching and keep a small overlap.

Stitch types and underlay interact with all of this; a fill's underlay often provides the hidden travel path itself. The stitch types and underlay pages cover those building blocks.
