Lay your wood cutout on the back of an unfolded table napkin sheet, and cut enough to cover the wood cutout.
Apply a thin, even layer of Mod Podge onto the wood shape, and then adhere your table napkin, taking care to avoid creases on the table napkin. Let it dry.
Once the shape is dry, apply a topcoat of Mod Podge to protect the surface from stains and make it last longer. Let that layer dry.
Once the wood shape is fully dry, trim the excess material, and use Mod Podge to seal the edges. Repeat steps 1-3 with the rest of your wood cutouts.
Thread wood beads on a piece of string. For my banner, I wanted to use six beads to separate each wood cutout.
Hot glue the string on the back of the cutout. You can cut a piece of paper to cover the string and make it look neater. Do the rest with the other cutouts, making sure that your bead count between each is the same.
