Rowesmay they are beautiful. May I ask what pattern is in your brain for the blanket? I have some yarn I thought would look good in this style but have never used double points before. So, I went to my lys and she looked up a particular cast on but the iPad wasn't loud enough for me to hear. She did the cast on and I started knitting but I think I twisted a stitch because I have a random bump! Will start over but thought you might guide me to an easy cast on.
I use the disappearing loop cast on. It makes a tidy center hole. Any square knit pattern that starts in the center will work. I add random purl rows and sometimes YOs. In this case I did a purl row with each color change. I sometimes do garter rows for one entire color. I just make things up as I go.
