I am a beginner and want to hand embroider my children's signatures on napkins. I have the hoop, floss, signatures and a way to transfer them onto the napkins. I don't know what the best stitch would be for this project. I want the signatures to be dramatic and think I want a very tight stitch. What advice do you have for me?
There are several "line" stitches that you could use when working on embroidered letters, Nancy.
There is the basic running stitch which would give a dashed line, but that may not be "tight" enough for you.
Perhaps the best known would be stem stitch which is often used in redwork embroidery. This will give a solid line and you could make it slightly wider by angling the stitches.
You could also try using chain stitch or split stitch, which resembles very close chain stitches.
