I installed my other piece of glass on top and hot glued it! Okay here’s a tip you won’t want to miss. If you want your flowers to move between the glass use something lightweight (like a soda pop or your phone) to lay on your glass while the glue is drying. If you want no movement use your bricks! YEP. Just make sure you don’t use to many your glass might break. LOL. I used 2 bricks for the 5×7 frames and 4 for the 8×10.
