Making anything for a guy is generally a challenge. The art of crochet does not lend itself to masculinity, in general. I think I've managed to make a scarf a guy would like and would actually wear. It's a very simple pattern and would look good in a variety of color combinations. If you look closely, you can see the long stitches running the length of the scarf. This particular scarf is for a Cleveland Browns fan.
7 rows orange, (7 rows brown, 7 rows orange) repeated. With 17 total blocks, the scarf measured 77" long.
Here's the pattern:
Chain 19, then work stitch 21.
I made this with I Love this Yarn in Brown and Orange with a J hook.
