In order for the sod to establish, it's best to start with freshly watered soil. It doesn't need to be soaking wet; just use a sprinkler to lightly moisten everything before you get started. Unroll the first piece of sod next to a driveway or a street. Line it up so that the edge of the sod is exactly aligned with the edge of the yard, with no extra dirt exposed. Carefully unroll the entire piece of sod so that the first long edge is covered. This provides a strong edge against which you'll lay the rest of the sod.  Starting from the middle instead will make it tricky to lay the sod in a logical matter without leaving any gaps or short ends. Make sure to roll each piece of sod in the same direction. If you roll a piece in reverse it will look very different from its neighbor, although they will eventually grow to an even appearance. Cut the second strip of sod in half lengthwise, and lay it directly adjacent to the first. Keep laying sod in a staggered, brick-like pattern. Laying sod in this fashion will make the seams less apparent later. Make sure that the edges of the sod butt up against each other without overlapping. Don't leave gaps at the seams; these exposed edges will be prone to drying out and leaving brown spots in the yard. Continue laying sod in this manner until the entire yard is covered and no seams are visible.  Use a box cutter to cut shorter pieces of sod where you need to fill in gaps or lay sod around corners. However, leave the sod pieces as large as possible. Don't cut them into smaller pieces unless you need to, since the smaller pieces are more prone to drying out before they get established. Seam all the edges by firmly rolling them together. Avoid walking or kneeling on the sod as you lay it, since this can cause air pockets and indentations to form. Laying the sod horizontally across the hills, rather than vertically along the hills, will prevent the hill from eroding. When the grass roots establish themselves they'll hold the dirt underneath in place. If you lay them vertically, especially on steep hills, you might encounter problems with the strips of sod bunching toward the bottom instead of staying in place on the hill. If needed, purchase sod or landscape "fabric staples" to pin the sod in place. Be sure to mark them clearly or paint them a visible color for removal once the sod has rooted. Since the key is to keep the sod in large pieces whenever possible, you can lay around curves by reshaping it instead of cutting it apart. Drape a large piece of sod next to the curve and pinch it together in a few spots so that the shape of the piece wraps neatly around the curve. Use your cutter to chop off the the raised areas that you pinched, and set aside the two smaller triangular pieces. Now you've essentially created two darts in the sod, allowing it to take on a semi-circular shape. Pull the cut edges of the darts together so that they lay right next to each other, with no gap remaining. If you encounter a tree or another obstacle you need to lay the sod around, drape it over the object and carefully cut the sod so that it fits around the object's base. Save the cutouts so you can use them if you have any small gaps to fill in later.  If you're laying sod around a tree, don't lay it right up against the tree's base. Laying it over the roots could damage the tree. Instead, cut out a circle so that the edge of the sod is a few feet from the tree.  If you have a lot of trees or other obstacles to work around, you might want to get a sod cutter to make the job a little easier. Cutting shapes out of the sod using just a box cutter can get time consuming.

One-sentence summary -- Water the soil. Start by laying sod along a long edge. Lay it in a brick-like pattern. Lay sod around hills instead of from top to bottom. Shape the sod around curves. Cut the sod to lay it around trees and other obstacles.

Problem: Article: When you get a new product, such as a chemical peel or even just a facial cleanser, it's important to patch test it first, especially if you have sensitive skin. Patch testing just means you use a small amount on part of your skin to see how you react.  In other words, you don't want to rub something all over your face or body and break out in hives everywhere. It's best to limit the area at first.  You should also skin test other products, such as shampoos, conditioner, and hair dyes. Basically, if you have sensitive skin, you should skin test any product that comes in contact with your skin. Your inner arm is a good place to test because generally that skin is fairly sensitive. In addition, it won't be too noticeable if you do have a reaction.  If the product burns or causes an immediate reaction, wash it off as quickly as possible. If it's a product such as lotion, leave it on your skin. If it's a product like a chemical peel that's meant to be rinsed off, rinse it off at the appropriate time. Wait a full day to see if you have a reaction to the product. A reaction could be your skin turning red, welting up, or showing a rash. You could also have scaliness or oozing skin. Another symptom is itchiness. Next, move to skin testing a more sensitive area. This time, pick a place where the product will be used. For instance, if you are using a facial cleanser, try it just under your ear in a small spot. The reason you need to test it again is because it may affect a more sensitive area of skin even if it doesn't affect your arm. Once again, wait for a full day to see if your skin reacts to the product. If it doesn't, you should be fine to use it.
Summary:
Understand product skin testing. Put a small amount on your inner arm. Wait for 24 hours. Test a more sensitive area. Wait another day.
