When you are making a blanket or scarf it is nice to have a stitch that looks equally good on both sides, if not the same. Some stitch patterns work better for this than others. What follows are some patterns that work quite well. Unfortunately, I only have pictures for four of the patterns listed, but cast on and make a swatch, if you use cotton these swatches will make a great dish cloth.
Note WS = wrong side and RS = right side.
