You can use the same puffer if you clean it out completely. I use a plastic box with a lid to hold my glue, flocking, and puffer. The box is big enough to set most of my projects in for puffing. After completely drying I turn the project over for the excess to stay in the box, by tapping, etc. then I can pour that excess back in the bag. For a different color I use a different box for a complete kit, including the puffer. It’s just a few bucks and saves a lot of possible frustration.
