Here's a simple horizontal scarf using one colour and made from soft wool donated to K4C last month. This was a partly finished item that I pulled down, skeined, washed and conditioned with fabric softener and recycled as a scarf for a homeless person. This is a variation on the Ingram scarf pattern - knit 2 rows; purl 2 rows - but using 12ply wool and 6mm circular needles. I cast on 210 stitches and used 150gms. The scarf measures 168cm x 13cm but would probably make it a little shorter next time.
