  • Pins

Print a word or phrase on printer paper in desired size and font. You can use our free download below, which includes the words Cheers, Gather, Thankful, and Welcome, or choose a word with personal meaning. Make sure your font size and typeface are large and thick enough that you can easily cut around the letters later with your styrofoam cutter. Once printed, carefully cut around the word with scissors.

Step 2: Pin and Trace

Pin stencil to a 18×12×1-inch rigid foam sheet so the edges are flat to the foam. Trace around the pinned stencil with marker.

Editor's Tip: To make art larger than a single foam sheet, trace the word onto multiple sheets and join the sections using toothpicks and Floracraft Styroglue.

Step 3: Cut Foam

Cut out the word with a styrofoam cutter. Work around the marker outline slowly for best results. Make sure to cut out spaces inside the letters as necessary. If you make a mistake and cut through a letter, use a toothpick to reattach.

Step 4: Add Confetti

Use a foam brush to coat the sign with felt glue. (Do not use spray adhesive, as this will melt the foam.) Sprinkle with shiny, colorful confetti or glitter and let dry. Repeat to coat the sides of your word or phrase and let dry.

Step 5: Insert Dowels

Insert two wood dowels into the bottom of the sign. Depending on the size of your word or phrase, you may need to use additional dowels. Use this sign as decor, a photo booth prop, or even as part of a centerpiece. To create an easy centerpiece, mount the dowels in a piece of scrap foam placed in a shallow vessel and surround with rocks to hold in place and hide scrap foam.
