Yeah, I looked at Eunny Jangs. I actually looked at several and tried various methods. I think the biggest problem was trying to work with dark yarn. I had a hard time seeing which stitch was which.
One thing that kind of messed me up was there are apparently a couple ways to do long tail for both knit and purl? Or maybe the technique to produce a look alike tubular is different. I don't know. I'm working in the round and regular tubular is generally done flat. I don't really have a problem with seaming that small section, but I wanted to try it in the round.
Maybe another time. I'm about ready to do the hem on the hat I restarted again.
