Can I use two pieces of mirror back to back in a window so it will look nice from both sides? Yes, you can. Like any pieces of mirror you use in a panel, youll want to use a sealant of some kind (ask your supplier for a recommendation) on the edges and back side of each piece before placing them back to back.

It’s official. Everywhere across the country, millions of young adults have flown the nest with bags packed, ready to begin a new adventure at college. It’s a great time for them to learn more about their studies, the world and themselves. College is also a place to make friends and develop a lifelong loyalty to a mascot that they will likely pay homage to in many ways. Some of those ways might not be so creative, like shouting out the window to a neighboring car with stickers from the same school. Or worse, shouting at someone from a rival university. Team spirit ignites such a passion in all of us who have attended school. Even many years later, you probably still cheer for your team. Passion is what fuels creativity. One of the best ways to express creativity is to use art as your outlet. Stained glass projects, mosaic patterns,
