It keeps rolling!

I’m doing the half linen stitch, and was forewarned that it would roll, so I added a 5 stitch seed stitch border on either side and it still rolls! How do I get it to stop? I really don’t want to have to change the half linen stitch because I like the way it looks and feels.

What are you knitting and what kind of yarn are you using?

I am knitting a dish cloth and I’m using knit picks CotLin.
