Chain piecing can help, you get a piece figured out and repeat it while it is still fresh in your mind :D:D:D
When I have taught this, I tell people to ignore the front of the foundation...it is just a sewing tool...the back is where all of the piecing is going on :wink: and back there it is being pieced together like any other block...
Print out a couple of extra block foundations...outline the block on the back side of the paper...holding it up to a light source while tracing, and use that as your guide. Write on it, noting which fabric goes where and again, ignore the front side.
Cut out the individual pieces of the second extra copy, put an X on the back and use them as cutting templates, lay them X side up on top of the right side of your fabric, add a 3/8" seam allowance all of the way around. When you get more comfortable with PP you can go to a 1/4" around each piece. Cut out all of your pieces, attach the template to them with a binder clip, start chain piecing :D:D:D
