Mosaic Flower Pots
The first step is to gather up the tiles you will need. Decide if you want a color theme or just a random pattern of color. You can use pieces of glass or flat glass marbles to add a little variation. You can use nearly anything--you're limited only by your imagination. Don't have any tiles? Use that mismatched tea-set you got from your Great Aunt Lilly!
The next step is to break the tiles or dishes. Go outside. Never try to break the tiles indoors unless you have a cement floor in your basement. Take the hammer, towel, newspaper, tiles and something to put the broken tiles into. Spread the newspaper out on the concrete, lay down the towel, lay one tile right side down and fold the towel over it. Hit it hard with the hammer a few times then lift the towel and check your work. Remove any pieces that are the size you want, then cover again and hit the remaining pieces. Continue to do that with all of your pieces. Be careful because the edges of the tiles can be very sharp. If you're breaking dishes, the edges are even sharper so be extra careful picking them up. After every few tiles shake the towel off into a bag to remove the tiny bits, as they can scratch the surface of the next tile.
When you have all the pieces you need, go inside and cover your work area with plastic or newspaper. Using an old butter knife or a tongue depressor as a spreader, pick up a piece of broken tile and spread glue generously on the backside. Press it into place on the pot. Pick up another piece and do the same, leaving a bit of space in between when you place the tiles. Continue until you are satisfied with the pattern and the pot is covered. Let it sit at least eight hours so it's completely dry.
You can buy different colors and textures of grout so purchase whatever you like. For indoor decorations I generally use decor grout in light grey, which is the most common color. Buy the powder form and mix it with water until it is the consistency of cookie dough or thick pancake batter. Wear plastic, close-fitting gloves (doctor gloves are great) because the grout is really hard on your hands. Do the mixing outdoors as the powder is really fine and tends to travel through the air as you pour it. You don't want to end up with gritty dust scratching up everything in your home.
After the grout is mixed go back inside. Have a bowl half-full of water and a sponge within reach of your work area. Grab a handful of the grout and start smooshing it in between the tiles. Really work it back and forth in all directions to work it down in to the cracks because you need to push all the air out. Be careful because the tiles can cut through the gloves.
As you are working don't let the grout dry out on your project. If you must, use the sponge and squeeze out a little water over the places that are drying out as you are working. Really pay attention to that.
When you've got the whole piece grouted, use the sponge to rub the grout off any tiles it may be covering and continue to work the grout into the cracks a bit. Not all the grout will come off of the tiles. You will be left with a film and that's okay. When you are finished and satisfied with how it looks make sure to dampen any dry bits and then cover it with some plastic. The plastic helps it dry more slowly. You want it to dry as slowly as possible, but don't go back and continue to dampen it. If it dries too quickly it will crack, and cracks are not good because it means that later on the tiles can fall off.
After 24 hours it should be completely dry. Remove the plastic and rub the tiles with a dry cloth. The grout film will come off and the tiles will be shiny. Once you finish rubbing the tiles you are all done! Yay!
*note: You will need to clean your supplies right away if you want to be able to use them in the future. Once the grout dries it is like cement. Do not clean your items indoors as you can end up clogging your drain in a really bad way.
