Magic Loop -- piece of cake. Can't say that I find it any more or less fiddly than DPNs, but it's nice not needing the extra bits. Increases -- took me a while to remember which way the bar goes on the needle -- had to sit with the laptop in front of me and play the vid for each increase to remind me for quite a few rows, but I finally got it.
I try to learn at least one new thing with each project, sometimes two or three new things, and don't think I'd manage it very easily without KH!
Have to say a humongous THANKS to Amy and Sheldon! In the absence of an experienced knitter anywhere close by, your vids and forum have been a lifesaver and really helpful!
