This is a bird house that I made for my mom's birthday. I started with a wooden bird house that can be purchased at any craft store. I primed the birdhouse with a 50/50 mixture of water and Weldbond PVA glue and then used Weldbond to adhere the vitreous tiles that were nipped into smaller pieces. I used a black sanded grout and a mosaic gloss sealer over the whole thing.
This bird house is strictly for decoration indoors
Below is another birdhouse I made for myself from the same store bought houses that you can find at the craft stores.
Here is what it looked like before grout.
Here is what it looks like after the gray grout.
