Large poster-board stars can make eye-catching decorations or signs, and cutting them out is simple and fast. The best way to get the outline of the star onto the poster board is to trace around a paper template--you'll get straight lines, good proportions and no erased goofs. There are printable star templates online that you can enlarge with a photocopier, or you can create your own design from large paper. Cutting a large star from poster board takes just minutes and yields a festive and useful shape.
Things You'll Need
1 sheet of standard poster board
Place the template on the poster board and lightly trace around it with a pencil.
Remove the template. Choose one of the star's outer points and cut inward along the pencil line. Stop when you reach the inner corner.
Cut again from the outside of that same point, along the second pencil line. Again, stop when you reach an inner corner.
Continue cutting in the same manner, always from an outer point to an inner corner, until the entire star is cut out.
Cutting only from the outside inward keeps the star flat. If you tried to cut the star out in one continuous line, the star would bend and possibly crease. You could also use a craft knife to cut out the star, but again, cut each line separately and only in one direction.
Use caution when working with scissors or a craft blade. Don't stack two sheets of poster board together to cut out two stars at the same time. One or both of the stars will have ragged or wavy edges.
