Invisible mending

Hi everyone,
I was wondering if there’s a truly professional business specializing in invisible mending in the Munich–Rosenheim–Chiemgau–Salzburg area. Quite a few people ask about it at my shop, and I’ve heard that tailors who offer invisible mending don’t really know how to do it properly. Customers then say, “I could have done that myself.”
Does anyone here know a professional who really knows how to do this?
Best regards,
Traudelina

So in Salzburg there is one single reweaving shop; unfortunately, I have no idea whether they can do it better than your seamstresses. I’ve never been there. Link.
What you can find about them online doesn’t look too bad, but that doesn’t necessarily mean anything.

Thank you, Ida.
I’ll make a note of this contact and pass it on if needed — but “with no guarantees.”
Best regards,
Traudelina
