Step 1: On a surface outside (I like to use a big cardboard box to hold the confetti and protect the ground), hold down your piece of streamer and spray.
Step 2: Quickly throw confetti over the streamer and press down if necessary. Use the leftover confetti in the box to apply it on the streamer again.
Step 3: Continue adding more spray and more confetti to cover up the whole streamer. Photography by Trisha Zemp
