A dear friend of mine wants to learn the star blanket pattern. Bonus, I've been wanting to learn this one too. She printed out the free pattern from Bernat.com and I brought it home to work on. It's a beautiful and simple pattern. Once you figure out the pattern it's easy and one you can work on while watching tv.
I found some nice mohair, baby weight yarn in my stash and had enough blue and white for this pattern. This is a pretty flexible pattern. Since you are doing rounds until it reaches the appropriate size, you really could use any yarn you like and it should work fine.
