Here are some that I did a few years ago:
This is the only kind of knitting I know how to do, LOL! These I did flat - going back and forth when I got to the end of each row.
And last year I did several in my daughter's cheerleading team colors (black, silver, & white) using those funky yarns, but I did them in the full circle so they looked like those "magic scarves" . They turned out great! I'll have to take a pic of Jordan's when I pull out the winter clothes this year.
