The starch is an old Navy wife trick for doing wallpaper on the cheap and not leaving marks when leaving housing. If I remember correctly, use the liquid starch (blue?) that comes in jugs from the grocery. Spread a thin layer on the way, then press your fabric into it. When you want to remove it, just wet the fabric, wash the walls, and presto! Back the way it was. Of course, we filled picture hanging holes with white toothpaste, too, so go figure! Oh, and the old wallpaper paste would bring bugs...wash the walls first with TSP to avoid that.
