I (plus a small workforce of family members) spent hours cutting out various stars and sprinkles from multi coloured fun foam, we cut them slightly larger than ideal but with the convention being 2 days away i’m happy to compromise on the scale of the sprinkles in order to get enough to cover the area needed.
Also because nothing would glue to the silicone we needed to figure out a way of attaching the sprinkles to the car…
This could become an issue
