Blind stitch hemming vs straight stitch for curtain making

Hello my dear sewing friends!!
A few days ago I saw how the curtains in our hotel were made and wanted to point out the correct sewing machines/ seams that we should use while making curtains. Technically, all stitching lines were straight and correctly stitched, but the correct sewing machine wasn’t used.
The regular straight stitching sewing machine is ok for sewing veils and very thin drapes ( even though it’s still not the best solution), but for thick / heavy drapes/curtains please use a blind stitch hem.
It will make a professionally correct, clean looking
seam and create beautiful drapes at the bottom line.

I am always learning something new. So interesting how the wrong machine for an industrial job can have such an effect.

Your discerning eye with attention to detail makes the difference between ordinary, assembly line looking draperies to professionally elegant, flowing draperies.
