Next step is to glue your flaps to begin completing the cup. You will need to hold them in place for a few seconds. I used regular Elmer's school glue. I tried hot glue but I don't think it's a good idea because it dries too fast before you can get your flaps into position and creates too many strings. All of you hot-gluers know what I mean.
After I finished my popcorn cups I created a little tag to glue onto the fronts using MS Word. I found a symbol that I liked and added text to the center that read, "A gift for you. Thank you for coming to my party." I printed several on a regular sheet of white paper, cut them out and glued them to the front of my cups.
Now, I needed to shop for the goodies that would go on the inside. I settled on Strawberry Nutrigrain bars, Dora the Explorer gummies, mini candy bars (Reese's, 3 Musketeers and Twix), Mini Fruit Roll Ups, and suckers. After I filled them with treats, I wrapped them in clear cellophane. I rolled out my cellophane and cut it every 21 inches. This length is approximate simply because I measured my first piece and then used that piece as a guide in cutting the rest of the cellophane. I eyeballed it first to figure out how much cellophane I wanted. After it looked the way I wanted I wrote down how much I rolled out before I cut. A roll of cellophane gave me 6 sheets, that's the cellophane I bought from Joann's. The cellophane I bought from the Dollar Tree gave me 8 sheets at 21" lengths for each sheet. I used 2 different shades of pink curling ribbon that I bought from Hobby Lobby to tie the tops.
I think they turned out wonderfully. If you have any questions on any of the steps I took in completing my popcorn cups just shoot me a message. I'd be more than happy to answer any questions. :)
