Okay, I have thought of two tips that might help. First, read the instructions over and over. They start to make sense after a while.
Second, you might consider making a small bargello to get the feel for the instructions. I made a placemat and it really helped me understand the technique. (Maybe I can find a picture of the placemat....though I don't use it as a placemat. I made it a "quilt" for my cat's basket here in the sewing room)
Okay, I found a picture. Notice it is not the same pattern at all, but I learned a lot by making the small version first.)
