you piece it like blocks set on point: diagonal rows.
Looking at the illustration, I would start by laying it out on your design board, or floor or bed. Start with the beige half triangle in the extreme upper left. Then join it to the burgundy diamond to the right of it. Now join the burgundy to the print diamond to the lower right (South East) of it, then the burgundy diamond to the lower right of that one, then the beige half triangle to the lower right of the burgundy one. That diagonal row is done. Proceed across the whole strip. now that you are a pro, create the short end rows. Now all you have to do is sew the rows together.
