Sure, it's really simple. First a word about binding off.
Here are the two neckwarmers I made last week side by side. I hadn't planned to take a photo of Mike's because it looked like Dad's but then I realized that wasn't true, they aren't exactly alike.
I made Dad's first, on the right, and used EZ's sewn bind-off. So why does the neckwarmer on the left flare out at the bottom? The bind-off is different, it's the last one in my list of stretchy bind-offs -- but I do K2tog tbl in Step 3 instead of regular K2tog.
Another difference is that one is K3P3 and one is K2P2 but gee, who cares.
OK, so here's the Easy Neckwarmer pattern (click to open in new window)
