The Hem

Most homeowners notice fabric first. A trained eye notices the hem. In the studio’s professional opinion the hem is one of the defining indicators of luxury custom drapery, because it quietly governs the qualities a client actually responds to — visual quality, proportion, movement, longevity, perceived craftsmanship, and the overall elegance of the finished installation. Two panels can be cut from the same fabric and headed the same way; the one with the correctly specified hem will read as custom, and the one without will not.

Our designer describes it this way:

The hem is the shoe of the drapery.

Just as the right pair of shoes completes an outfit — finishing the line, grounding the proportions, signalling the level of care behind every other decision — the correct hem completes the drapery. It is the detail that anchors everything above it.

The studio standard

For most floor-length custom drapery our studio specifies a 4-inch (10 cm) double-fold hem, built from approximately 8 inches of fabric allowance at the bottom of each panel.

We recommend this construction because, across most natural-fibre face cloths in Los Angeles interiors — linens, cottons, mid-weight wools, silk blends with proper interlining — it is the construction that hangs the most consistently over a decade of use. A doubled 4-inch hem gives the bottom of the panel enough mass to hang plumb against the floor without rippling or kicking out. The double fold conceals the raw edge inside the hem, so no selvedge or cut edge can ever telegraph through the face fabric under raking light. Eight inches of allowance leaves the panel adjustable: it can be let down if the floor finish changes, taken up if a rug is added later, or re-hemmed in a future room without compromising the panel.

Custom construction, not mass manufacturing

One of the studio’s core positions is that industry standards are professional starting points, not final specifications. Every project is evaluated against the architecture, the fabric’s behaviour, the room’s proportions, the desired appearance, the function the drapery must serve, and the long-term performance expected of it. Construction is then specified to that project — not duplicated from the last one.

Custom drapery should be treated like bespoke tailoring rather than mass manufacturing. A tailor does not finish every trouser the same way; a workroom should not finish every panel the same way either.

Fabric determines construction

A second studio principle follows from the first: construction techniques are selected according to the fabric. The fabric’s weight, hand, weave, and behaviour over time govern how the panel is built — how it is headed, how it is hemmed, how it is weighted, and how it is lined. Construction should never be standardised across every project.

Alternative hem techniques

When the chosen fabric will not behave correctly inside a doubled 4-inch hem, the studio specifies an alternative. These techniques do not replace the standard hem on projects where the standard hem is correct; they are the right answer for a different fabric.

• Blind stitch. A near-invisible hand or machine stitch used where the face fabric must show no stitch line under raking light — silks, fine cottons, and the most considered linens.
• Slip stitch. A hand-worked stitch used inside a folded hem on fine cloths where mechanical stitching would dimple the face.
• Fine rolled hem (Euro hem). A narrow, hand- or machine-rolled hem used on lightweight sheers — organza, fine voile, performance sheers — where a 4-inch doubled hem would be too heavy and would distort the fabric.
• Bonded or fused hems. Used selectively on technical or performance fabrics whose face cannot tolerate a stitched hem, and on certain commercial and hospitality programs where IFR or wear-cycle requirements govern the finish.

Concealed bottom weight chains

The studio routinely specifies concealed bottom weight chains sewn into the hem allowance of the panel. A continuous chain weight at the bottom of a drapery panel encourages the fabric to hang plumb, eliminates the small kick that lightweight or very full panels can develop at the floor, and gives the hem a consistent line across the full width.

Lightweight cloths benefit most: fine linens, lightweight cottons, sheers, organza, and silk blends; tall panels where the fabric’s own weight is not enough to hold the line; and layered systems where the inner sheer must move independently of the outer drapery without flaring.

The chain is encased inside the hem behind the lining, so it is invisible from both the face and the back of the panel. The client never sees the chain. They see the result, which is a drapery that settles into its final position quickly when opened or closed, resists the small air-current ripples that otherwise read as a “nervous” panel, and protects the hem’s geometry over years of use.

Project lesson: Glendale

A homeowner in Glendale wanted to preserve a panoramic view, install sheer drapery, and combine it with a blackout system on the same windows. The fabric they were drawn to was a lightweight organza — a sheer too fine to carry the studio’s standard 4-inch double-fold hem. A doubled hem on that fabric would have distorted the bottom of the panel, telegraphed through the face under raking light, and fought the sheer’s natural fall.

Our designer specified a fine rolled hem (Euro hem) with a concealed bottom weight chain sewn into the hem allowance. The rolled hem kept the bottom of the panel as light as the rest of the fabric; the weight chain settled the panel against the floor and held the line. The blackout was engineered as a separate layer behind the sheer, so the view-day fabric never had to do two jobs at once.

Header construction

The same principle governs the top of the panel. Our standard recommendation is approximately a 4-inch header for most pleated drapery — enough body to draw the eye cleanly across the top of the panel and enough structure to hold the pleat shape over years of use. For some projects, particularly inverted-pleat drapery on tall ceilings or tall windows, a deeper header of approximately 6 inches creates better architectural proportions. A shallow header on a twelve- or fourteen-foot panel looks under-built; a deeper header reads as deliberate and lets the panel anchor the wall.

Header construction depends on style, architecture, scale, and design intent — not on a default specification.

Designer quality control

Construction decisions of this kind — header depth, hem specification, weighting, interlining, and any non-standard fabrication — are personally specified by Olga Rechdouni, ASID. Where the project warrants it, she also reviews fabrication and installation quality on site to ensure the finished panel reflects the approved design intent before the client sees it. Quality control is treated as an integral part of the House of Drapery by Duroque methodology, not an optional service.

Common hem mistakes

The hem is where construction shortcuts become visible first. When the studio inherits a previously installed treatment for repair or replacement, the most common patterns we see are:

• Uneven hem lengths across a row of panels — usually the result of measuring one opening and duplicating the dimension across windows that look the same but are not.
• Insufficient weighting. A hem with no weight chain, or corner weights only, will kick out, ripple in air movement, and read as under-built within months.
• Poor stitching at the hem. Visible stitch lines on the face of fine cloths, puckered hems, or mechanical stitching used where a blind or slip stitch was required.
• One construction applied to every fabric. A 4-inch doubled hem on organza, or a fine rolled hem on a heavy interlined linen. The hem must answer to the fabric.
• Evaluating drapery by fabric alone. Two panels in the same fabric can read entirely differently depending on construction. Fabric is only part of the read; construction is the rest.

Why this matters

A drapery is one of the longest-lived elements of a finished room. The decisions made at the bottom of the panel — how it is hemmed, how it is weighted, how it meets the floor — are the decisions the room will live with for a decade. They deserve to be specified to the fabric, the architecture, and the function, and the reasoning made visible to the client. That is what the hem is for, and that is why the studio takes it as seriously as it does.
