@nittas_homeandstyle begins by using a large rectangular canvas as her base, employing several foam pool noodles (available from Dollar Tree for $1) to form her design. She lays out her desired shape of the final piece, which involves several different lengths of foam in a wave pattern with longer and shorter lengths. After measuring out the length of each piece, she cuts down the pool noodles with a knife. Because the adhesive from any stickers may leave residue, @nittas_homeandstyle reminds users to make sure any remaining stickiness is on the unseen part of the foam, as it may affect the painted finish later in the project.
Using Mod Pod, apply a liberal coat on the canvas with a larger brush, making sure to work fast before the glue dries. starting in the middle, lay out the foam pieces on either side, affixing them to the canvas with ModPodge and to each other with a stronger adhesive like E-6000. Apply the rest of the pieces of foam to finish the design. Once dry, the sculpture is ready for paint. @nittas_homeandstyle uses a posh gold spray paint to cover the entire piece, then uses gold washi tape to finish of off the end of each length of foam.
