Question Sewing Labels into Knitted Items

Hi… My name is Georgette I have been crocheting for 10 years and Knitting for a year … I’m obsessed with Knitting and can seem to give anything away that I have made even though when I was knitting it I had someone in mind. So I feel if I put a label in all my items I will feel better about letting them go … I also take pictures of all my stuff as well… Please help I ordered labels … how should I sew them in… tried by hand horrible outcome. Use a machine or does someone out there have some cool technique. Please advise

I think that if it was me, I would try again by hand, just catch the corners and the centre of the label, by a sort of slip stitch, in the same colour cotton as the garment that you have made.
