I have never used a file! I think I need to get educated in them. Do they only work if you have a silhouette or can use use them with a regular printer?
For die cuts, I’ve got tons of freebies so I do my own. I have bought a few die cuts for the files tho. I usually have my cricut draw a title if I do one. Sometimes I will weld together the letters and cut them that way.
Tamara, depending on how sophisticated the machine is (I think) they will print the die cuts and cut them out for you even. I think the newest versions of cricut/silhouette both do this.
