I just finished an entrelac project and I used the knitting backward method. I liked it better instead of all the turning. I was making a scarf and I did to a little turning at the very beginning and very ends of the rows, but not for each individual diamond section. If you don't know how to knit backward, here is a great link to a YouTube video on how to do it.
Entrelac is actually very easy once you get the general idea down. Good luck and I can't wait to see your finished shawl. The pattern is very nice.
