All you need to make this is a styrofoam ball, tissue streamers, and hot glue. For a tutorial go here: http://www.theidearoom.net/2011/01/tissue-rosette-kissing-balls.html
I also made this Valentine canvas! I bought the wood letters, white canvas, and 1 page of Valentine scrapbooking paper. I modge podged the scrapbook paper on the canvas then painted the letters red and hot glued them onto the paper. Very easy and not expensive!
So as you can see, not much to it! Anyone could do this!
