I agree, I just spread glue stick glue all over an area and slowly sprinkle the confetti, sometimes moving pieces around slightly if they arent distributed enough. Then I try to lightly press them down with my fingers so they stick better.

To make rustic-looking confetti, gather some paper or cardstock in a variety of colors and rip it apart with your hands. If you want a finer confetti, fold the papers several times and cut them into ½ inch strips. Then, turn the strips 90-degrees and cut them into ½ inch squares.
