A way to make outside edges tighter?

someone told me once a way to make the outside border stitches (like on a scarf) appear tighter, but I’ve since forgotten the tip. I think it had something to do with a slipped stitch but I can’t remember. Can anyone help? Thanks! Ellen

i like to slip the 1st stitch of each row in gt and st.
in seed and ribbing, i just make sure to give the first stitch an extra tug.

Yup. Slip the first stitch on each row as if to purl. That’s the way I was taught.

You need to slip the first stitch in every row and knit the last stitch even on the purl rows and that makes i look exactly the same on both sides.

I came across another way, which might be called a `chain selvedge’? You slip the last stitch on the row purlwise with the yarn in front and knit the first stitch (which is the one you slipped).
