A Carft Knife is necessary to make very precise/accurate/exact cuts and can be important when trying to weed out small pieces of paper that get left when making cuts using your Cricut machine. They can also be used to cut materials other than paper that you want to put into your scrapbook projects.
Here are some pages that I have used my X-acto knife in the creative process:
- How to preserve football helmet stickers
- Sophomore Year Football
- How to create an opening folder on a scrapbook page
