For my wedding that is in less then two weeks I was trying to make my own centerpieces. I made a silhouette of my fiance and I and tried to use posterboard to cut them out. I am having a problem cutting them out because the center of the paper is white so and if the cuts aren't exact the top layer of paper is ripping and the white is showing through. I am not sure if I should be using a different kind of paper, or if i am using the wrong kind of cutting tool. The paper needs to be thick enough to stand up, it should be about 12 inches tall. i have even started trying to look for like a printing place that would be able to do it but I am not having any luck because i am not sure what I should be looking for.
It seems that some of these scrapbook machines might be able to do what I want but I am not going to buy a machine just to make 16 center pieces.

any help would be amazing
