Paint bats, spiders and spider webs with black window paint on a plastic sheet. Let the paint set for a little while.
Fill in details with yellow and red window paint.
Let the design dry for 24 hours.
Remove the design from the sheet and put it up on a window or a mirror for Halloween.
With window paint, the kids can make fun and maybe slightly spooky Halloween decorations. When the designs are dry, they essentially become stickers that you can put up on windows and mirrors. The window paint tube has a fine tip, making it easy to paint anything from fine lines or large areas. Tip: Place a sheet of plastic over a drawn design and use it as a template.
