Customize your entry with frightful bats or whatever spooky shapes and Halloween phrases you would like.
Use a marker or pencil to draw a small or medium-sized bat silhouette directly onto the sheet of painter’s tape. If you don’t feel comfortable drawing freehand, look online for bat shapes or other shapes, like pumpkins or cats.
To ensure that the mat will not become hard and crusty and that the bats will keep their shape, use textile paint. Brush it on in short up-and-down strokes to make sure that the shapes stay sharp and crisp. Note: A specialty spray paint made for textiles may also work for this project if you have a time crunch. But keep in mind that the reverse-stenciled bats may not be as crisp as if you were using a brushed-on paint.
