Problem: Write an article based on this summary: Slip the needle into the fold, then draw up through the top crease. Using the end of the needle, grab a few threads of the fabric just above the fold. Put the needle back into the fold. Repeat Steps 2 through 4 as many times as needed. Tie off.

Answer: Don't put the needle all the way through the fabric and then bring it back, as you would in traditional sewing. Instead, guide the tip of the needle under three or four of the textile's threads. Weaving the stitch this way will prevent obvious bunching or pulling on the outside of the garment. Close to where you drew the needle out of the fold, point it back in, keeping the needle parallel to the fold. You'll be moving lengthwise along the fold as you continue. When you're finished sewing the hem, tie off such that the knot is located inside the fold.

Problem: Write an article based on this summary: See your primary care physician. Stop taking medications that could be to blame. Alter your hormone replacement therapy. Ask your doctor for a prescription hydroquinone cream. Talk to your doctor about a second skin lightener.

Answer: Talk to your primary care physician about any hormonal medication changes and creams you can try for melasma before going to see a dermatologist. Treatment for melasma may be considered elective and it may not be covered by your insurance. Find out the costs of any treatments and procedures before you schedule them. Certain medications, like birth control pills and hormone replacement therapy, can affect your hormones and induce melasma. Talk to your doctor about stopping these medications. Even though pregnancy is the condition most commonly associated with melasma, melasma has also been known to occur with medications and conditions that impact your hormones. Oral contraceptives and hormone replacement therapy are the next two most common causes of melasma, after pregnancy. You can stop use or try switching to a different product to determine if your melasma will fade naturally afterward. Often, it is impossible to stop a hormone replacement therapy. Consider why you are on hormone replacement therapy to determine if you may be able to stop or adjust the dosage. However, there are ways that you can change your therapy so that it is less likely to cause melasma. Consult with your doctor before making any changes. Begin taking hormone replacements at night. If you take the hormone replacement in the morning, it will be at its peak potency when the sun is out, maximizing the risk of melasma. Shifting your regimen to the night can help alleviate the problem. Creams and patches might be slightly less inclined to cause melasma than oral versions of the treatment. Ask your doctor to administer the lowest dose feasible. While some treatments containing this ingredient can be purchased over-the-counter, your dermatologist or primary care physician can prescribe a stronger version that will be more effective at lightening the skin. Hydroquinone comes as a cream, lotion, gel, or liquid. It works by blocking the natural chemical process in your skin responsible for creating melanin, and since melanin produces dark skin pigmentation, the amount of dark pigmentation related to melasma will also be reduced. Prescription hydroquinone typically has a concentration of 4 percent. Concentrations of hydroquinone higher than 4 percent are unlikely to be prescribed in the United States and can be dangerous. They can cause ochronosis, a permanent form of skin discoloration. While hydroquinone is used as a first treatment in many cases, your dermatologist might be willing to prescribe a secondary skin lightener that can help enhance the effect. Tretinoins and corticosteroids are among the most frequently used secondary treatments. Both are used to speed up the body's process of shedding and replacing skin cells. Some dermatologists may even prescribe "triple creams," which contain tretinoin, a corticosteroid, and hydroquinone in one formula. Other options include azelaic acid or kojic acid, which slow down the production of skin-darkening pigment.

Problem: Write an article based on this summary: Scan for moisture inside walls with a moisture meter. Find the cold, leaky part of a wall with an infrared camera. Cut into your drywall to find the source of a leak.

Answer:
A moisture meter is a piece of equipment which, when placed directly against a wall, will analyze the moisture content of that wall. If you know that you have a leak within a certain wall, but are unaware of the precise location, place the moisture meter at 5 or 6 different spots on the wall. Whichever spot gives the highest moisture reading is closest to the leak. You can purchase or rent a moisture meter at a large hardware store or home-improvement store. These gadgets are frequently used by professional home-inspectors to find leaks or wet walls. Infrared cameras detect heat, and can indicate the temperature of a wall. A leaky, wet wall will have a cooler temperature than the surrounding wall. Train an infrared camera on a wall with a leak, and look to see which section of the wall is the coldest. This will be the section of the wall nearest the leak. When using an infrared camera, hot objects will have red or orange coloring, while cool objects will have blue or purple coloring. You may be able to rent an infrared camera from a professional contractor, a home-improvement center, or from a photography shop. Use a utility knife to score a line about 10 inches (25cm) long into your drywall at the location where you see visible signs of a water leak (mold, discolored drywall, etc.). Then, using a drywall saw, cut along the line you just scored. Cut a hole in the wall large enough for your head to fit inside. Stick your head in the wall and look around until you spot the source of your leak. Enlarge the hole so that you can also insert a flashlight to see better inside the wall, if needed. Often, the patch of wall which shows signs of a leak is not directly in front of the leaky pipe or fixture. Water can drain along the outside of pipes in your walls or trickle many feet down the inside of your walls before the telltale signs of a leak become visible. Both a utility knife and a drywall saw can be purchased at your local hardware store.
