e.ridenh: If you try to add a border without a drop, it will keep the stitches from dropping. Why don't you knit a a fee rows using the pattern to see? Yes, you can add crocheted side borders after you are finished. Works perfectly. But, when you crochet across the dropped stitches, you have to make several crochet stitches in each drop so you don't distort the drop. The best thing to do is forget side borders if you are using any kind of drop stitch. If those dropped stitches are comming from garter stitches, you don't need a border because it isn't going to roll. The scarf I made from lasso stitch was all lasso, no rows of garter. There is nothing but open stitches and it's plenty warm because when you wrap it around your neck, there's a lot of yarn there. You can't pull it up over your nose to keep the wind out though, so it's limited in its uses.
