Once you’ve trimmed the roll, wrap the fruit roll up around it (squeeze). Green fruit roll-ups would be best, but I couldn’t find them. I left the plastic wrap on my roll-up while I applied it to the candy, none of the kids bothered to do this. It works well both ways, just make sure to remove it before cutting.
