This is how I usually prepare for a balloon clip that involves lots of balloons. The night before I am usually up editing and uploading a new clip and get an idea for a new clip. Then in the excitement of said idea I go threw my stash and start setting aside the ones I will need. Then instead of waiting till the morning I immediately start blowing them up, which in this case ended up being 23. Satisfied with my nice little assortment of sizes and shapes my upload has finished and I head off to bed with visions of balloon popping in my head. Only to blow up even more tomorrow.
