Someone (I don’t remember who—sorry!) recently gave us this nifty piece of advice, and I’d like to pass it on to all of you: bandage/medical scissors work really well for cutting cardboard. We used them for our marble maze and cardboard hands at Maker Faire, and they were great. I also tested them on Popsicle sticks, and they cut through those pretty easily, too. (Though, I’m not sure how quickly Popsicle sticks will ruin the blades. Also, pieces of Popsicle stick went flying, so safety glasses are a good idea.)
We ordered ten of these, and so far they’re getting the job done.
Let us know if you have other tips, tricks, or ideas.
