Do you finish each cross stitch one at a time, or do you do a row of half crosses then go back and complete the stitches in the row? I used to work lots of half crosses, then go back over them with the other half cross. Now I tend to complete each stitch at a time.
I find it’s easier for me to be sure I have really completed all of the stitches. My vision is getting weaker so checking all of the little stitches to be sure they are all finished was driving me mad. This way, I know that I have completed the stitch and I think my work looks a little better.
