nupps on a plane

I was really excited for our ten plus hours worth of flights back to the States, because I love knitting on planes and was hoping to get through my much neglected Swallowtail Shawl, which I started on the plane ride to Peru and then pretty much didn't touch for three months. I was making pretty good time, too, until I hit the dreaded nupp section. I'd never knit nupps before, but figured I could just follow the instructions and everything would be okay - right? Which was fine, until I got to the purl row, which literally took me an hour. I had to pick up the stitches with my fingernails to purl them. 

Fortunately, we landed in Houston for a connection not long after, and I was able to look up nupp techniques on my cell phone. The most useful one I found was, while making your nupps by K1, YO, K1, YO, K1 into the same stitch, just YO twice for each YO; then, on the purl row, you can slip those YOs into one really loose stitch, which makes the purling insanely easier. After that, I was actually looking forward to making nupps, though this shawl is still littered with mistakes - so here's hoping they're not too noticeable in the end?
