My friend has recently begun looming and selected scarves as her project of choice. We have found that using a single strand of yarn on the blue Knifty Knitter and knitting a flat panel works nicely. A skein of Red Heart or Homespun makes a scarf that is 18 stitches wide and 60 inches long. There is usually a little left over so I've been crocheting hats to go with her scarves.
Elena is modeling a set made with Red Heart Fiesta.
Here the scarf is made with Homespun that has a gold thread in it.
And this set is made from JoAnns Rainbow Classic Pattern yarn.
