Scoring time saving trick

I have been cutting up a lot of cards lately for my CF workshops and orders that I've gotten. Scoring every card individually is very time consuming. I figured out that if I score a piece of 8 1/2x 11 cardstock before cutting it that I can score 2 cards for the same amount of time that it takes to score 1!! This also works if you are making a number of 3x3 cards. Just take a piece of 12x12 cardstock and score it at 3 inches and 9 inches. Then you can cut the paper at the 6 inch mark. Turn it and cut the scored paper at 3 inch cuts. You now have 8 cards scored in the time that it usually takes to score 2! Hope this helps some of you out. I never realized when I was just taking workshops how much time it takes to cut out the projects.
