Y'all are welcome!
Bootie - Not really, since you primarily use card stock or the heavier papers to make these. They're pretty sturdy. Many models also make use of internal support structures or formers, especially the rockets, which greatly aid in durability and strength. My Saturn 1B sruvived a move halfway across the US unscathed

Mehlsack - Awesome! I hope you enjoy it. Let us know what you decide to build! If you have any questions about making one, feel free to ask. Also, I'll go ahead and recommend a few tools for the job (you probably have most of this laying around):
Card stock or a heavy paper, preferrably 32lb/120gsm and above. I use the plain old card stock that can be found in office supply or craft stores. Can't remember the specs on it.
Cutting Mat
X-Acto knife with plenty of blades
Scissors
Sobo Glue or Aleene's Tacky Glue - I primarily use Sobo since that's what we used in design school to make our models. Quick setting, dries clear and is pretty flexible. Both are usually available at art/design supply stores.
Toothpicks
Tweezers or small pliers
Different diameter rods to form the card stock - My go-to forming rods are a toothpick, a K98 cleaning rod and a ballpoint pen for small to medium sized parts. For large parts you can usually form them by hand.
Patience - The great thing about paper modeling is that if you mess up, all you have to do is print out another parts sheet. I'm no stranger to doing that
