We get asked this question all the time! The funny thing is, it really varies per person. If you are “duct-tape happy”, you may go through much more than someone who uses it sparingly. 😉
A very rough estimate is probably 3-7 rolls of duct tape per book, depending on which book you are using, how many projects you are doing, and what accent colors you use to decorate your handcrafted weapons and armor.
