I have found in PP it is easier to work with batiks because the difference between right side of fabric and the back is, for the most part, indiscernable. This makes the whole "working in reverse" less problematic for beginning PP. The placement of your first piece on the paper is right side up on the wrong side (back side) of your paper pattern, this is before you have done any sewing. I have found this first placement to be easier if you have a sunny window or a light source to hold the pattern with one piece of fabric so you can see your stitching line through the fabric and you can ensure the fabric covers the entire unit on your paper pattern with seam allowances. You take your second piece and place it right side down on top of your first piece. Sometimes it is easier to pin for this first seam. Then flip the whole thing over so your fabric is on the bottom and your paper is on top and stitch on the line. Take the unit out of your sewing machine, flip it over, trim your seam allowance if necessary then press piece two out and ensure it covers your next stitching line by 1/4". If it is larger this is the step where you fold back the paper at stitching line #2 and trim to 1/4". flatten out your pattern piece again and place fabric piece 3 to line up with your freshly trimmed edge, right sides together and flip the pattern again so the fabric is next to your feed dogs and the paper is facing up. Stitch seam two and continue repeating the steps. Essentially with PP you are assembling a mirror image. Once all done, the paper is on the back of your block.
Here is a good link to make a practice block in PP with step by step directions with pictures. Maybe this will help you?
