Short answer. Yup. They can be.
If you make a lot of projects that are specifically to inspire or if you make things that are designed to make things look cool, Cricut can help with that. I know my family uses them constantly for projects check those two boxes or that never see the light of day. It can be used to pretty much do anything.
Just recently I’ve made labels for supplies in my craft room, artwork for the kids bedroom, confetti, lunch bags and homework books for school , shirts for a friend’s kids first birthday party, decorations for a super hero party, paper flowers for a gender reveal party, shirts for a dinosaur themed party, and several other random cut files for friends.
