Just like with a drywall ceiling, failing to repair the leak will only result in having to repeat the repairs.  Make sure to wear protective equipment as you do repairs in the event mold has grown due to the moisture. If your popcorn ceiling was installed prior to 1979, it may contain asbestos.  In such a case, it may be better to contact a professional to conduct the repairs. If it's an old stain from a long since repaired leak, you may be able to simply bleach or paint the ceiling to cover the stain.  Try using a one to one water and bleach mixture to remove light stains.  Make sure to wear protective glasses and gloves while applying the mixture. For darker aesthetic stains, simply primer the spot to seal it and cover it with a matching shade of ceiling paint. Due to the moisture, it should scrape off fairly easily.  Remove the popcorn material from the affected area with an extra inch or so on each side. Scrape it until only the flat drywall is visible.  The drywall may also have water damage on it. Wear safety glasses and a dust mask to protect yourself from the falling material. You may not need to cut out or repair the water damaged drywall.  If the drywall is merely stained, you can seal it with a product like KILZ paint that will prevent the damage from spreading and serve as a seal.   The damaged drywall will not be visible after you apply new popcorn material. If the water damage to the drywall is substantial, follow the repairing a drywall ceiling steps above to repair it. As long as you’re certain the drywall is sound and dry, you can simply apply new popcorn material to the affected area.  If you repaired the drywall, ensure it is dry, sanded and clean so the popcorn material has a sound surface to stick to. Use the ready-made popcorn material that comes in a tub.  The spray can be difficult to control for small applications.  Try your best to match the thickness and texture of the existing popcorn material on the ceiling. Once the popcorn material is completely dry, you can paint the repairs to match the existing ceiling paint.  Painting the entire ceiling will ensure the color matches throughout.

Q: As soon as you meet a new person, jot it down. Also, include other facts about him or her that you recall. List the time and place that you met him or her, as well as actions he completes or interesting information that she mentioned in your conversation. Writing down these facts will help you recall her name, especially since you have a physical reminder. Also, it will also give you a source to refer to if you meet her again.  Large events may not give you the chance to instantly write down names, especially since many introductions may be made. Instead, insert important names into your phone. Later, you can refer to them and add interesting facts that will help you recall them. Another excellent method is to  leave yourself an audio message. You could also create a virtual file. Create a document or table with people's names on it. Add to it each time you meet a new person. Share the file with all your devices in order to always keep a physical reminder with you. Take the person's name, and turn it into a picture in your mind. Associate the name with an object. For example, the name Crystal could be identified with a large crystal vase or bowl. A visual connection can be a powerful tool when recalling names. This also works with names that sound similar to a concept. For example, you have a new man at work named Miles. You can associate him with a picture of a a long road that goes on for miles. When you first meet someone, study her face. Look for a feature that is unique and associate her name with it. For example, you could identify the new employee in your office by her dimples. This method will put her face into your head and help you remember her name. An excellent method to remember a person is to think of an absurd scene in relation to him. For example, if you meet someone who owns a pet grooming business, think of him surrounded by dogs in crazy hairstyles. A humorous image will help you recall his name, as well as a specific fact about him. The more ridiculous the image, the more likely you are to remember it.
A: Write down the name. Create a mental picture. Find an unusual feature. Imagine a ridiculous scenario.

Article: Mold and mildew love warm, damp environments, so store your comforter in a spot that will stay cool and dry. Try to pick a spot that's off of the ground and indoors. Stay away from sheds or other outdoor storage locations — bugs have an easier time accessing these spots. A linen closet is the best option for storing your comforter — it keeps it off the ground and in a clean closet. If you don't have a linen closet, you can also store your comforter on an extra shelf or in a clean cabinet.  If you have a piece of furniture that acts as a storage container, such as an ottoman, you can store your comforter there. Storing your comforter in a plastic bin is fine as long as it's sealed in a protective bag as well. To prevent the feathers in your down comforter from being damaged, don't put anything on top of the sealed bag. If the comforter will be going in a closet stacked with several other things, place the down comforter on the very top.

Look for a cool, dry location. Choose a linen closet or similar spot, if possible. Don't store anything on top of your down comforter.

Article: Set your oven to 325°F (163°C) and let it heat up. The process of seasoning cast iron involves coating it with a layer of oil and baking it. Seasoning, or curing, the pan will cover it with a non-stick surface, make the pan easier to clean, and protect it from rust.  Most new cast iron pans come pre-seasoned, but you'll have to season any that haven't been cured by the manufacturer.  You can still season a new pan if it comes pre-seasoned, and you should definitely season an old or second-hand cast iron pan before using it. Fill a sink with a small amount of hot, soapy water. Immerse a clean sponge in the soapy water, then wash the cast iron pan. Rinse the pan under hot water and dry it completely with a clean towel.  You can also use a dish brush with stiff bristles to clean the pan. Most people recommend not washing cast iron with soap once it has been seasoned, because the soap can slowly remove the seasoning. However, because you're about to season the pan, use soap now to make sure the pan is clean. Dip a clean cloth or paper towel into some vegetable shortening. Rub the shortening over the inside and outside of the skillet to coat the pan with a thin and even layer. It’s best to use a small amount of solid shortening for seasoning, because too much shortening or using liquid oil can leave a sticky residue on the pan. Place a cookie sheet or piece of foil on the bottom rack of the oven. Then place the skillet upside down on the middle rack. Bake the empty skillet for an hour. The baking sheet is important because it will catch any shortening that melts and drips off the pan. After an hour, turn off the oven. Leave the skillet in the oven as it cools, about one to two hours. Remove the pan from the oven once it’s cool. Buff the pan by rubbing it with a paper towel or clean cloth to remove excess shortening. When you're finished, the pan should be a smooth and shiny black. Over time, this non-stick layer may wear away, especially if you use the pan to cook non-fatty foods. Repeat the seasoning process every few months, or when:  The pan loses its luster and becomes dull The color changes from black to dark gray Food starts sticking to the pan
