What Are the Ladder-Like Open Joins Between Fabric Panels Called?

Fagoting connects two folded or otherwise finished edges with thread while leaving space between them. The open area is part of the finished design. Threads describes the technique as a decorative join for fabric or lace, and Janome’s instruction book explicitly uses the heading “Fagoting” for joining two fabric pieces with an openwork appearance. Threads: Try Machine-Sewn Fagoting for an Heirloom Embroidered Look, Janome: HORIZON Memory Craft 9410 QC Instruction Book, printed page 122.

The term describes a joining technique rather than one exact arrangement of thread. A straight-rung version can look like a tiny ladder; machine-worked versions can have a more decorative pattern. Consequently, the appearance alone does not tell you whether the join was sewn by hand or machine. Both approaches are demonstrated in the Threads articles. Threads: Vintage-Inspired Neckband, Threads: Machine-Sewn Fagoting.

Start by examining the join’s reverse side and following the edges along its length. The following comparison is a practical identification aid derived from the documented construction methods. Treat the clues as guidance: a distant photograph may not reveal enough detail for a definite answer.

What you can see	Most useful term	Construction clue
Threads cross directly between two finished fabric edges	Fagoting or an openwork joining seam	The connecting threadwork is worked between the edges
A distinct trim strip has its own borders, with fabric attached along each side	Ladder lace insertion	A separate piece of lace forms the open strip
Bundles of the fabric’s own threads form a ladder inside a continuous piece of cloth	Ladder hem stitch or drawn-thread work	Threads are withdrawn and the remaining threads are grouped
A machine accessory holds finished edges apart while decorative stitches connect them	Spanish hemstitching	A spacer controls the gap during stitching

These distinctions follow Seamwork’s separate-trim tutorial, the Royal School of Needlework’s drawn-thread instructions, and Brother’s description of a Spanish hemstitch attachment. They describe different ways to create an open effect, so search using the construction you can actually observe. Seamwork: Ladder Lace Insertion, RSN StitchBank: Ladder Hem Stitch, Brother: F090AP Spanish Hemstitch Attachment.

Use ladder lace insertion when a separate openwork trim joins the panels. In Seamwork’s tutorial, the required materials include two fabric pieces and the ladder lace itself. The fabric is stitched to the lace edge, and the seam allowance is finished using a rolled and whipped seam. The ladder structure therefore comes from the trim rather than joining stitches made across an empty gap. Seamwork: How to Sew a Ladder Lace Insertion.

This distinction matters when gathering supplies. If you want to reproduce a detail with a visibly separate border along each side of its rungs, begin by looking for ladder lace insertion trim. Compare the border construction and open section with your reference before choosing a width. If the threadwork instead runs directly into folded panel edges, a fagoting tutorial is the more useful starting point.

Seamwork’s method first attaches one lace edge with the right sides together, then trims and encloses the allowance before pressing it toward the fabric. That attachment process is a useful clue when examining an existing garment: look for the seam that secures the trim to the panel. Seamwork: Ladder Lace Insertion Tutorial.

The phrase ladder stitch needs context. DMC uses “Ladder or Slip Stitch” for a variation also called invisible ladder stitch, used to attach appliqué or bind seams. Searching only for ladder stitch can therefore lead to instructions for a concealed attachment rather than a decorative open join. DMC: Step by Step Embroidery Stitch Guide.

Ladder hem stitch has another specific meaning. The Royal School of Needlework describes it as a hem-stitch variation worked at both ends of the vertical threads in a drawn-thread area. Its instructions group the same clusters of remaining fabric threads along the two opposing edges to produce the ladder effect. RSN StitchBank: Ladder Hem Stitch.

For identification, trace a rung into the surrounding cloth if possible. A rung formed from the cloth’s remaining weave points toward drawn-thread work. An added thread connecting two separate finished edges points toward fagoting. A rung contained within a distinct inserted band points toward ladder lace. This construction-based check is more informative than matching the ladder silhouette alone.

Yes. Janome’s HORIZON Memory Craft 9410 QC manual gives a machine-fagoting method: press under each fabric edge by 1.5 cm, position the folds 0.3 cm apart on paper or tear-away backing, and sew so the needle catches both folded edges. Remove the paper after stitching. These are instructions for that machine’s documented method, so use your own manual for stitch selection and settings. Janome: HORIZON Memory Craft 9410 QC Instruction Book, printed page 122.

A useful first sample follows the same sequence:

1. Prepare two scraps with the edge finish intended for the project.
2. Secure the edges to temporary backing at the gap specified by your machine’s instructions.
3. Select the documented joining stitch and presser foot.
4. Sew slowly, checking that the stitches catch both edges.
5. Remove the backing and inspect the unsupported join before sewing the project.

The decisive check is whether both edges remain connected after the temporary support is gone. If stitches miss one fold, correct the alignment or spacing before continuing. If the sample puckers or the opening becomes uneven, keep working on the sample rather than assuming the backed version shows the final result. These checks follow directly from the manual’s requirement that the needle catch each folded edge.

Spanish hemstitching is another useful term for machine-made decorative joining across a gap. Brother describes its Spanish Hemstitch Attachment as joining ribbons or finished fabric edges with decorative stitches, using a guide or spacer to maintain the space between them. This makes it a relevant search term when you want an accessory-assisted method. Brother: F090AP Spanish Hemstitch Attachment.

Check the attachment instructions and machine compatibility before selecting equipment. Brother’s cited product description specifies compatibility with 7 mm stitch-width machines; that specification belongs to the listed attachment and should not be applied to every machine or hemstitching accessory. The accessory name can help you locate a method, but it cannot establish how an unidentified garment was made. Brother: Spanish Hemstitch Attachment Specifications.

Choose by the structure you want to reproduce. For a separate, repeating ladder band, investigate insertion trim. For visible joining threadwork directly between finished edges, investigate fagoting. For an open band made within the existing weave, investigate ladder hem stitch. This sequence keeps the material choice tied to the construction.

If you want prominent individual rungs, Threads provides a hand-worked example: a first pass of ladder stitches joins a prepared neckband to the garment, and a second pass wraps each rung with thread. It demonstrates why a ladder-like join may be called fagoting even when the initial connecting stitch is described as ladder stitch. Threads: Learn to Make a Vintage-Inspired Neckband.

Before committing to a longer join, make a sample that includes the actual fabric and edge finish. Threads recommends testing on scraps and identifies lightweight to medium-weight woven fabrics as a useful starting point for machine fagoting. It also emphasizes finishing or hiding the raw edges, including options such as narrow hems, tucks, or fabric tubes. Threads: Try Machine-Sewn Fagoting for an Heirloom Embroidered Look.

For the familiar open ladder between two panels, start with fagoting and ladder lace insertion. Examine whether the rungs connect the panel edges directly or belong to a separate trim strip. That single observation usually gives you the most useful wording for your next tutorial search or materials enquiry.
