knit eternity scarf this year, my sister-in-law was a lucky recipient as well. For this knitted eternity scarf I used a cotton and a cotton/bamboo mix yarn. I love the color combination. I decided not to use a continual pattern and just mixed it up between double knit, knit and purl etc. Nothing too fancy, but the lack of pattern I find really pleasing on the eye and makes it unique.
Why don't you give it a try? Cast on and knit-purl for a while and then double knit, double purl...see what happens. What is the worst that could happen?
You may real like how it turns out!
