Step 4: Sealing the Finished Product
Since this project is made of paper, sealant is needed to harden and strengthen the bowl and coasters. Using the water-based sealant (Mod Podge) and a paintbrush, generously cover the bowl and coasters to ensure that all parts of the paper are glued together and becoming sturdy. I used one coat on my coasters, and two on my bowl. I recommend covering the inside first so it can dry while sitting on its base, then when the inside has dried, flip it over and seal the outside. Mod Podge dries clear, so don't worry about being generous on the coating.
Once the coasters are dry, you can spray them with the water-proof sealer so they can be used for drinks. They may need to be re-sprayed from time to time, since they are made of paper and are being used for drinks.
Once the pieces of art are dry, they are ready to be used! If you decide to make more, you can experiment with different shapes. A friend of mine made a triangle shaped bowl and square coasters, the sky's the limit! Enjoy your new pieces, and be prepared for them to be a conversation starter!
