Step 2: Scoop out a bit of Mod Podge with your paintbrush and water it down a bit so the texture is thinner. You don’t want it super drippy, just a bit thinned-out. I mixed it up right in the lid of the Mod Podge container.
Step 3: Start affixing the punched-out paper shapes to the glass using your paintbrush. Tissue paper is so thin that you can actually pick up the pieces using the wet paintbrush if you like. You could also brush Mod Podge onto the glass first, and then stick on the paper shapes. Either way, brush over the shapes afterward to fully saturate them with Mod Podge. Wet tissue paper can rip easily, so try not to get too rough with it. Take your time and brush gently, attaching more and more shapes, overlapping them however you prefer. Once your glass is fully covered, set it aside to dry.
