My dh has a JD from Duke and is working on his MLS (yay!) from Carolina (Go Tar Heels!). The rivalry scarf was born out of a need to show off both the dook and the UNC loyalties without necessarily picking sides (it’s fairly obvious which one I’d pick anyway, and luckily he’s not a big sports fan). It’s a perfect scarf for a football game - warm wool, good dimensions for under a coat or on top of a sweatshirt, fringed but made manly by the alternating garter ridge stripes. Just be careful if you do it in rivalry colors - you may not be welcome in either camp!
This is an excellent scarf for those of you looking for some color variation but not ready yet for fair isle or intarsia. Because you carry the alternate color up the side, the only ends to work in are the beginning/end of each skein, but you still get experience juggling two skeins at once. It would be easy to add in one or two additional colors to shake things up (like, Crimson for our ABs!).
