Specialty Repair
Invisible Seams Helsinki
Nearly invisible weave repair for wool, cashmere, silk, and fine cotton. The repair you do not want anyone to notice.
Invisible mending is a craft inherited from a time when clothing was expensive and replacing it was not casual. The technique rebuilds damaged fabric by realigning the original fibers and weaving along the original grain, producing a repair that, on the right fabric, is genuinely hard to see. We use it on wool, cashmere, silk, and tight-woven cotton for pieces worth keeping long enough to repair.
Invisible repair is slower than standard mending. Expect seven to ten business days and a higher price point than a visible repair. The trade-off is a result that preserves the look and value of the piece.

How It Works
- Step 1
Book an Assessment

- Step 2
Assess and Quote
We quote the repair and tell you honestly what final result to expect: nearly invisible, discrete, or visibly repaired.
- Step 3
Repair in Studio
Fiber-matched and weave-matched work done slowly by hand. Thread drawn from inside seam allowance when possible.
- Step 4
Pickup
Ready in seven to ten business days for most invisible repairs. Complex heirloom work takes longer.

Frequently Asked Questions
Will the invisible repair really be invisible?
On the right fabric, yes. Tight-woven wool, cashmere, silk, and fine cotton hide repair well because the weave can be rebuilt. On very loose knits, heavily textured fabric, or worn fabric, the repair will be strong but visible. We tell you honestly at assessment which category your piece falls into.
Does invisible mending work on knit sweaters?
Often yes, especially on tight knits in wool or cashmere. Loose or open-knit sweaters sometimes show the repair more. A quick assessment in person confirms what result to expect.
What fabric does invisible repair work best on?
Fine wool, cashmere, tight cotton, silk, and tightly woven suiting fabric. These fabrics have enough fiber density that the repair can blend in. Denim, linen, and chunky knits are better suited to visible mending, which can also look beautiful.
How durable is an invisible repair?
As durable as the surrounding fabric, and sometimes more so because the repaired section is reinforced. Proper care (gentle washing, appropriate pressing) keeps the repair sound for years.
Can you repair moth holes in a cashmere sweater?
Yes. Moth hole repair on wool and cashmere is one of our most common invisible mending jobs. Most moth damage repairs very well.
