If you can knit a scarf, you could knit an afghan, potholder, a shawl, and probably a sweater. (I am always trying to convert the word to knitology, you know!)
I have the first set of socks that I was making for my niece's kids done, and I started a scarf pattern, in acrylic yarn, but before I go any further, I am going to start it over in a different yarn, probably a real wool, maybe in a lace weight or fingering. It will be very lacy. I started it out k1 the first row. then start the pattern:
slip first stitch. (p1, k1 yo, k2 tog across) k the last stitch.
slip first stitch. p across until the last stitch, k that.
slip first stitch, k across.
It makes a corrugated pattern, totally reversible. with rows of lacy holes.
But before I do that, I have to start the socks for my grandniece, now that I have finished the ones for her brother.
I started a shawl the other day, a simple garter stitch shawl for my great-grandma, in a shiny cotton yarn; It's very pretty. I've finally grasped the concept behind YO, which helps. ;-P
