Article: Once you've removed the current wall dressings and wall items, like light switch covers, you'll want to check the base layer that you will be building on to make sure that it is structurally sound. This is important, since a rotting or weak wall can cause your tiling job to warp, crack, or even break and fall down.  Look for signs of mold or damage to the tiling surface. Cracks are often a sign that a wall may be weak and need to be replaced. Try pressing on the wall, especially at the studs. If it gives way or feels soft, it may require work. If you are going to be tiling a large area, remember to use tiling board as a backer and not just put the tiles directly onto drywall. Tiling board is installed just like drywall (nailed to the studs) but is made of more water resistant materials which will keep it from warping and cracking your tile work. Now, using a level and measuring tape, measure and mark for the middle lines in the area you will be tiling. You want to find both the vertical and horizontal middle, since you will use these to keep your tiles straight and divide the area into sections for tiling. Never assume a fixture in the room like the tub or vanity (or even the ceiling) is perfectly level. They rarely are. It is very important to rely on the level. Using a chalk snap line, mark the mid-line and vertical lines which you just measured. If you've never used a chalk snap line before, don't worry: it's easy. Simply place a nail at one end of the space you marked, attach the string, pull it taut and snap it down. This will leave a straight line on your wall. You'll still want to check it for level but it's much more accurate than drawing a line. You can use just regular string and manually chalk it to make a chalk line. Using  a chalk box may be easier as these take less work - you can buy one for about $5. Dry fit your tiles to be sure that they will look the way you want them to look. Once you're comfortable with how it looks, figure out how the tiles will meet up with the corners and edges of your wall. You will probably need only a part of a tile when it comes to some of these areas, so it will be necessary to cut the tiles to size. Measure how much space you need for each row with the spaces and cut tiles to size using a diamond tipped wet saw.  So, for example, let's say your wall to tile is five feet long. You're putting up subway tile and the tiles are 6", with spaces of 1/4" between each of them. You'll need 9.6 tiles for each row to cover that space, meaning nine full tiles and one cut to 3.6" If you don't own a diamond tipped wet saw, you can usually rent one from your local major hardware store. You can also use a tile cutter, but this is more likely to end in broken tiles so only take this option if using cheaper tiles.   Dry fitting is especially important if your tiles make up a pattern, since you will need to be very comfortable creating that pattern. You don't want to make a mistake or have to spend a lot of time thinking about it once the mortar is up on your wall. You can test your dry fit pattern by making a layout stick, which can be made from any straight and level piece of spare wood. Lay the tiles on a floor and mark the layout stick with a pencil at the joints between tiles. Use the layout stick to see how the tiles fit on the wall. With everything else ready to go, you'll want to install a batten to help keep your tile rows straight. This is a piece of scrap wood, such as a piece of 1x4 lumber, that you use as a long straight-edge, placing the first row of tiles right against the batten. Align the top edge of the wood so that it follows exactly along the mid-level line that you marked, then screw it into the studs. Once the tiles have been placed, simply unscrew and remove the batten. Double check that everything is level before installing the tiles on the batten. You'll also want to check it all the way across, since there may be dips in the wood you use for your batten.

Make sure your wall is ready to go. Use a level and tape to measure for your tile locations. Mark the locations on the wall using a chalk line. Dry fit and then cut tiles to size using a diamond wet saw. Install a batten to keep your first row straight.
Article: Before you pull out the keyboard and start typing in URLs, do some research on products, prices, and availability. There are two types of gold that are commonly traded: bullion and coins.  Gold bullion can be in the form of coin, or those bars you picture when you think of Ft. Knox (most often "London Good Delivery" specification). Bullion is pure gold, and is priced only by the amount of gold involved. Gold bars are recommended more for “big league” investors or collectors. Investing in this type of gold is more effective, except for the purpose of selling. Because bars cannot be subdivided, options for buyers are limited. Gold coins—or numismatic gold—are more collectible, have a lower threshold for entry into the investment market, and are easier to cash in. Because they can be collectible—and often mixed with other metals—their price can fluctuate more than the price of bullion. Determine before you talk to a sales associate just how much money you can comfortably afford to spend on gold. Without fiscal parameters, you could easily spend more than you had intended. There are websites that post daily gold prices and provide periodic price updates throughout the day. Some sites list gold prices in several currencies, including the Euro, Japanese Yen, Swiss Franc and the Indian Rupee. The better dealers will also include market research and analysis articles on their sites.  A fair price will always reflect the current nominal value of gold. What is called "fair market value" will reflect the nominal value as well as the present supply of and demand for gold. Most gold bullion will have a small markup above  the spot price (the instantaneous market price). A smaller purchase will entail a larger markup in terms of percentage compared to a larger purchase. Gold coins will be priced significantly further above spot price than will bullion.  This is because coins tend to be more collectible and have a higher secondary-market demand. Expect to pay a premium for that. The rarer the coin, the higher the premium. However, for the most common of coins you may not encounter a premium. A good deal is defined as one that fits your budget.
