The paint spreads as it dries, keeping that in mind the smaller the design the better. We enjoyed the window cling option for the paint a few did not stick for some reason. In concept this kits seems like such a great idea, but thinking about the cost, time to dry, and how the paint spreads which can effect design, I wish it was priced cheaper. I say 3 stars but gave it one extra because at the end of the day it was a fun activity that we all got to do together as a family. Making memories that will last longer then the ornaments.
