This is what I am trying to knit, it is called Skywalker. I bought Video lessons from Craftsy.
I have always wanted to make a lace shawl but I didn't understand the grid patterns of today.
This was well worth the money as it is well explained, but still difficult.
In one section I undid what I had done 5 times!! But Laura Nelkin is very good and showed how to do a life line in your knitting. This is where you thread a contrast yarn through a row of stitches so if you have made a mistake you can undo to the life line which holds the stitches.
It isn't easy and I consider myself an experienced knitter, so as well as learning lace knitting, I am learning patience (grrrrr!!) and persistence!! LOL
I am about a quarter way through and will post a pic next time.
