Article: Anytime you pick up flowers from the store or florist, you'll want to refresh the stems by trimming them an additional half an inch or so, even if they've already been cut. This also applies to flowers that have been delivered or cultivated in a greenhouse. To put it simply, always trim and prune fresh flowers, no matter where they came from. Get in the habit of dumping out and replacing the water in your flower vase every morning, or as soon as it starts to get murky. Fresh flowers need a lot to drink, so don't hesitate to top off the water level if you notice it getting low. Be sure to add a pinch of plant food to help your flowers flourish. To refill the water in large decorative arrangements, tilt the vase over the sink to empty it, then run fresh water over the stems using a watering can or measuring cup. Waiting too long between waterings can lead to rot, which causes the blossoms to wilt and produces an unpleasant smell. Since cut flowers have been separated from their root system, they won't be able to survive as long as they would in the soil (no matter how fresh they are). You can prepare your flowers for their new environment by sprinkling half a packet of organic plant food into the vase prior to inserting them. Plant food contains essential nutrients as well as antimicrobial additives to slow the growth of mold and bacteria. You can purchase plant food at any gardening center or greenhouse, or in the home-and-garden section of most supermarkets. Alternatively, you can whip up your own plant food at home by combining 1 tablespoon (14.8ml) of sugar, 2 tablespoons (29.6ml) of lemon juice, and 1 teaspoon (4.93ml) bleach and adding them to 1 quart (0.95L) water. Pour the mixture into the vase. Most types of flowers fare best in mild, moderate conditions. Temperatures between 65F (18C) and 72F (22C) are ideal, though a couple of degrees higher or lower shouldn't make too much of a difference. Make sure your flowers get plenty of sunlight, but situate them away from the most intense glare to keep them from overheating. Some heartier species like roses and orchids prefer a warmer environment. It's safe to store these flowers in hotter areas, such as your kitchen, or even outdoors on a sunny day. It's fine to keep your flowers' water at room temperature. You can also try adding a couple small ice cubes to the water, which may help the blooms survive a little longer.

Cut precut flowers again as soon as you get them home. Change the water daily. Add plant food to the water to keep the flowers nourished. Keep your flowers somewhere cool.

Problem: Article: Don't preheat the oven; you want your plates to slowly warm along with the oven. Introducing room temperature plates to a very hot oven can make them crack or shatter completely. You can put your plates on a baking pan or directly on the oven racks. The plates will have warmed up to this temperature along with the oven. This allows the paint to "cure," or set into the ceramic. If your ceramic paint instructions suggest a different temperature or baking time, follow that instead. Once the oven temperature has reached 325F (163C), leave it on for 40 minutes. You can set a timer on your oven, phone, or a watch to keep track of the time. Most ovens will beep when the chosen temperature has been reached, so set a timer at that point. You want the temperature of your plates to slowly cool down along with the oven. If you handle the plates too early, you can break them. Cooling times depend on your oven but wait at least 2 hours before checking the temperature. Be patient and don't touch the plates while they're still cooling in the oven. Since your oven should be completely cooled, the plates should be cool to the touch as well. You can use oven mitts to remove your plates to be safe. Put your plates in a place where they won't be disturbed by children or pets. Let them rest for at least 3 days before you use them or wash them. Hand wash them for the first time. While washing them, you can check your painted designs and make sure the plates were not damaged while baking in the oven.
Summary: Place your plates in a cold oven. Let your oven reach 325F (163C) while the plates are inside. Leave your oven on for 40 minutes to let the plates cure. Turn off your oven to let your plates cool. Remove your plates from the oven once the oven is cooled. Allow the plates to rest for at least 3 days before using or washing them.

Though it may be tempting to pop a zit or pick at your acne, doing so can cause the skin to become even more inflamed and lead more acne as well as acne scars. Instead, make sure you wash the area well and apply skin care products that will work to treat and heal your acne. Never use any sharp tools on your skin, even if it is advertised as an acne removal tool. This can lead to permanent damage to your skin that can be difficult to treat or that will require more intense skin care treatments to heal. If you have a habit of resting your chin, cheek, or forehead in your hands, try to avoid doing this. If possible, try not to touch your face at all throughout the day. Your hands are carriers of bacteria and germs that may only make your acne worse if they end up on your face. As well, if you tend to have oily hair or if you have longer hair, keep it clean and away from your face. Oil from your hair can make your face and neck extra oily, leading to possible breakouts and acne in these areas. Avoid wearing baseball caps or hats throughout the day, as these can cause acne to develop on your hairline or your forehead. Wash your caps and hats often if you wear them on a daily basis so they do not carry any bacteria that can get onto your skin. Make sure your cell phone is clean, as you can get breakouts where your phone rests on your face. To make sure you are removing dead skin cells from your skin that can cause acne, you should wash your face twice a day, once in the morning and once at night. Use a cleansing product that contains salicylic acid, benzoyl peroxide, or glycolic acid to treat your acne effectively. Avoid scrubbing your face hard with a washcloth when you clean your face. Instead, use your fingers to gently massage the product into your skin. If your skin is very sensitive, then wash with a gentle facial skin cleanser such as Cetaphil or Eucerin. You should also always wash your face after exercising or playing sports as oil buildup due to sweating can make your acne worse. If you are starting to grow facial hair, you may be tempted to start shaving. However, shaving can irritate acne-prone skin and lead to more breakouts. As well, you may end up nicking a pimple while shaving, which could cause inflammation. If you do need to shave, try to shave as lightly as possible on the surface of your skin to avoid irritating your acne. If you are using a safety razor when shaving, soften your facial hair with warm water and soap before you shave so you do not have to press too hard on your skin. Though your skin may appear better after a day out in the sun, in the long term, sunlight can actually make your acne worse and lead to sun damage on your face. As well, many acne products can make your skin more vulnerable to burning. Protect your skin by applying oil-free sunscreen before you go outside, even if it is not sunny outside. Many commercial acne products can dry out your skin, especially if your skin is still trying to get used to the ingredients in the product. To prevent dryness or chapped skin, use a moisturizer that is oil-free and noncomedogenic. This will ensure the moisturizer does not clog your pores or irritate your skin. Avoid using moisturizers that are heavy in oils, such as Vaseline and mineral oils. These products will only increase the buildup of oil and debris on your skin and make your acne worse. Ask your dermatologist to recommend an oil-free moisturizer, based on your skin type and the severity of your acne.
