I think that a lot depends on the type of font, fabric, and density used to stitch your name. If the font has wide dense stitching on it, may leave holes. You might try stitching a small line... 1/4" length .straight.line.a on ithe jacket where it would be less noticeable. Remove the stitches and see if it left holes or not. I've had good luck with just laudering fabric to remove holes too.
