Pour a liberal amount of Mod Podge (available at craft and hobby stores, Target, etc.) onto a disposable container, like a plastic lid. Use the sponge roller to begin rolling the Mod Podge onto the old fabric surface.

Make sure that you roll the Mod Podge thinly and evenly, otherwise you will have possible bleed-through on your fabric. Work quickly so you cover the whole panel before the Mod Podge begins to dry.

Use the foam brush to spread the Mod Podge to the edges of the old fabric panel and into the corners.
