1. Select the motifs you wish to use. They should fit the stone fully if possible. Then tear around the napkin motif, being careful not to damage the motif itself. Tearing the motif instead of cutting it gives it a more natural look when applied.
2. Apply a light coat of decoupage glue onto the stone and press the napkin carefully onto the stone. Use the flat paint brush and apply a light coat of decoupage glue on the entire napkin. Start at the center of the napkin and work towards the outer edges and smoothening out the wrinkles if any occur. The glue will saturate the napkin and adhere it to the stone. Be careful not to press the brush to hard onto the napkin. Once the glue has saturated the napkin, it can tear easy.
3. Let the glue dry before continuing.
4. Once the glue is dry, dip the sponge into the paint and dab the sponge on the stone and all around the napkin motif so that it blends in with the stone as much as possible. Let the paint dry and then the stones are ready for use.
