Over at CRAFT a little while ago, Becky Stern posted this cool pattern for a scarf featuring the iconic O RLY? owl. I have no arguments with the pattern itself: I'd wear that scarf! It's awesome and hilarious. However, in terms of the execution, there are some technical issues worth discussing, particularly since Becky said that she wasn't completely happy with how the scarf came out.
If you want a scarf that has two good sides and the correct tension, it must have reversible stitches. The most common reversible stitch in scarf knitting is garter stitch, but there are myriad other possibilities.
It is not possible for a flat, single-layer scarf done in stranded or fair-isle knitting to have both a clear image and two good sides (you can see that the O RLY? scarf, as made, does not have a completely clear image). By definition, "stranded" means that strands of the yarn not in use on particular stitches are carried across the back of the work.
There are two "correct" ways to make the O RLY? scarf in which it will be reversible and not have visible yarn floats. A third technique is available, but would probably require redesigning the pattern significantly. All of these techniques take much more work than a flat, single-layer scarf.
Read more about it after the break, where we'll discuss various ways to use color charts in small accessories like scarves, bags, and pillow covers, and whether or not you should really worry much about doing things the "right" way.
