great job---your effort and hard work will pay off
they do make glow in the dark stuff from stencils to paint...here's my story
we bought our place here in the ozarks,,and had just moved.the house was still kinda new to us.and as my mother came from Iowa to visit ,we put her in a spare bedroom that one of the previous kids had.as she prepared for bed and then shut off the light,she was surprised to find that as she lay down,,,the ceiling was covered with glow in the dark stars and a message...."you are being watched"....i guess she slept ok,,,but that is how we discoverd glow in the dark!!
good job
