I'm backdating this a little, since it's a reference and not meant to be a new post.
Criteria for this list: Knitted (that's all I'd be qualified to comment on), Beginner/Easy, Unisex (too many scarf patterns call for Fun Fur (not unisex) or are decidedly feminine*). Honestly, all you have to do is pick out your yarn (for the love of whatever diety you worship, please leave the Fun Fur in the drawer), get the right size needles, cast on enough to get 5-8" width and knit and knit until it's long enough. The following list is for those who'd like to try something different, but don't know where to start.
*We all know that unisex means "stuff guys would consider wearing." If the words fuzzy, lacey, loopy, frilly, etc. could apply, then it's definitely not unisex. If your brother, husband, son might wear it, then it's probably safe. Let's make it easy on the folks putting the packages together by sticking to materials and patterns that either gender could wear comfortably.
- Start here, at Martha Stewart's Basic Scarves
- Mistake Rib Scarf - how perfect that I finally found a good overview of this stitch in an entry about the ('06) Red Scarf project! This is a wonderful stitch for any gender, and shows off both plain and self-striping yarns beautifully! (A pic from another source.)
- Sideways Garter Stitch Scarf & Simple Ribbed Scarf - Basic beginner's scarves, with the guesswork (math) taken out of it. I've done a few of the Sideways scarves, not necessarily following the pattern, but maybe if I had followed it, I wouldn't have a 7-foot long scarf and be out of yarn before I cast off.
- Orange Bliss - If you aren't going to use Cashmerino Superchunky, the simple ribbed scarf at the link above would be all you need.
- Bulky Sideways Scarf. Calls for Noro Iro (very pretty!), but would work with any bulky yarn that would knit up on size 11s.
- Big Wool Scarf
- Misti Bulky Scarf - Seed stitch with BIG needles. You'd just need to make it a little longer.
- Another sideways-knit scarf: Brother-in-law Racing Stripe Scarf, for a stripe pattern idea. (formatting is messed up, but it's still legible)
- Misti Alpaca Diagonal Rib Scarf (PDF)
- Super-Long Ribbed Scarf (from the book Knitting Pretty. Another cool scarf - Ribbed for His Pleasure - is in the book Stitch and Bitch.)
- Seeded Rib Scarf -- similar to the mistake rib with wider ribbing
- One-hour scarf (3 or 4 yarns together, knit sideways) - would recommend either adding fringe all along the edges or skipping the tassels.
- Organic Cotton Man Scarf (substitute a slubby worsted-weight wool)
- Yarn Harlot's One Row Scarf
