Looking for a job: Soft furnishing - sewing repairs

Hello, I am new to the site and just wanted some local advice on where I can take a pair of red silk curtains to be invisibly mended?

There is a slight tear, about 6cms, on the edge where the curtains join (don’t know the technical name for this) but I really like the curtains and would prefer to get mended if at all possible?

Thank you for your recommendations. We are in the Carvoeiro / Lagoa region.
