"Right now we're going to talk about your substrate. Substrate is just a fancy word for whatever you glue your glass pieces to. For this project, I've chosen a small wooden picture frame. This is a great beginner project. It becomes something functional and useful and it's also not too big because mosaicking can be a time intensive project. I've chosen a wooden frame which is great for mosaics, you're welcome to use any woods you would like to use. However, if you want to think about your mosaic lasting for a long time, you want to treat the wood. So, you can buy a wood sealer at any hardware store and seal the wood. Just make sure you wait twenty-four hours from when you seal the wood to when you start gluing things to the wood because it needs to dry completely. You can also mosaic a lot of other objects such as faces or plates, an end table, or a kitchen table. Or, you can make just fine art pieces for indoors or outdoors with glass. Just remember, if you are mosaicking something for the outdoors, wood, even if it's treated is not the best material to use as a substrate. Because it's porous, it will expand and contract with the weather and that expansion and contraction will make your glue weaken and make your glass fall off. Think about other things that you can mosaic outside such as flower pots or metal tables or even your cement retainer wall."
