So I wanted to mention to you that I actually started doing these shirts as flowers, not fireworks. That gives this project a longer season so it's not too late to fire up the fireworks. I mean flowers. Flowerworks?
... a sun. I made this shirt with my Zippy when she was about 6 years old (oh my, half her life ago!). She wanted a little flowerbed for her shirt, no bugs. You can see that these shirts do eventually fade so it's important to heat-set them as best you can.
