Knitting: Bella's Mittens

I'm slowly trying to build up my knitting skills, and decided to try to knit a pair of mittens.  The pattern to these mittens can be found here.  I learned how to use the magic loop and also how to complete a thumb! Let me tell you, learning the magic loop instead of use double-pointed needles was so easy and priceless.

The best instructions I found (in my opinion) to learn the magic loop can be found at Knitting Daily.  It's not a video tutorial, but it does go picture by picture.

For finishing the thumb gusset, I used a YouTube video to get me started by Kelley's Mittens Class.  There were quite a few useful videos on this channel.

What has been your favorite pattern that has taught you some new techniques?
