Today I got a raffle ticket which is used for our seminar party last night. The ticket was torn in half by scissor so that one half is in the rolling bucket and the other half is the guests' hands. The ticket itself is made from a soft, thin white paper.
What I want to do is: Recreate this "complete" raffle ticket as if it was never been cut in half, in other words, is there any way to "fuse" two piece of paper(of same type) side by side so that it forms one big piece? The dashed line between the two piece is intact in this case so that the fusing part does not involve any pictures to worry. Obviously tape should not be used in this case and using glue could end up messy. If I crudely put them together firmly a noticeable seam can be seen.
Actually I find this a very hard thing to do (some people think cutting a paper is irreversible, thus impossible). Maybe someone with professional knowledge or with paper making theories can tell me that is there a way to achieve a flawless result?
