Here are "exploded" versions, if it will help you see better which blocks go where, That's not narrow white sashing between the blocks, but just blank space in the picture.
I found it easiest to piece this if I worked a row at a time. I printed out my pattern and folded it so only one row was visible at a time. Since rows #1 and #17 are identical, I worked on two rows at once so I could chain-piece them. Same with rows #2 and #16, and so on. Only the center row, #9, has no duplicate.
