I think these are awesome! If you have a fan in your room and want to decorate (cheaply) just go to the dollar store and get some patterned tape! You can actually put this tape on pretty much anything!
I am so glad I just saw this. Make raised letters for craft projects: print out the font you want and place wax paper over it. Trace letters with puffy paint, let dry, then use mod podge to secure letters to canvas, etc.
