Scoring is another paper-centric word that pops up pretty often. Scoring is simply the process of adding a crease to a sheet of paper or cardstock so that it folds more easily. There are simple, inexpensive hand-held tools made for scoring and then there are also machines (around the size of a paper cutter) that take on larger jobs with less elbow grease. Adding the crease helps to keep the paper and ink from cracking, giving the piece a smooth, professional finish.
Scoring is a big help with all types of projects from a simple bi-fold to the more complicated French folds and accordion folds. People love holding and handling paper, especially when it has some sort of interesting construction or shape. Often a little creativity with the paper folds is an inexpensive way to squeeze a lot more visual interest into your piece without a lot of money. Score!
