Look at the veins on your wrist. If they appear green, you have warm skin. If they appear blue, you have cool skin. Another way to determine your skin undertone is to see how easily you suntan or burn. If you tan easily, you likely have warm skin; if you burn easily, you probably have cool skin. Knowing your skin's undertone is important. If your makeup does not match your skin's undertone, it will look make you look too ashy or yellow. Some companies sell contouring kits that are labeled for warm or cool skin. In this case, buy the one that matches your undertone. If the kits are not labeled, purchase a yellow-tinted kit if you have warm skin, or a pinkish kit if you have cool skin. Gold and bronze shades are good for warm skin. Nutty or woodsy hues like mahogany and walnut are better for cool skin. Many contour kits work well for both warm and cool. You should also think about if your skin is light, medium, or dark. Using a palette that is too dark looks fake. Contouring kits are just a set of pressed powders that are a few shades lighter and darker than your skin tone. This means that you can use just about any pressed powder, such as foundation or blush, as long as it works with your undertone and tone. Eyeshadow tends to be more intense in color than other powders, so it's harder to work with. If you do use eyeshadow, choose matte for your shadows and either matte or shimmery for your highlights. Do not buy loose powder. Use pressed powder; it is easier to apply. Bronzer is too shimmery and won't cast natural shadows. Illuminator is also too shimmery. While you can use it above your lips or on your cheeks, you don't want to use it in areas that will get shiny, like your nose. Using illuminator on your nose will make it even more shiny. Camelhair brushes will work the best, but you can use other brushes that are soft and fluffy. Have a selection of large, small, and medium brushes. Blush and angled contour brushes work great here. Do not use brushes with stiff or synthetic bristles, such as lipstick or foundation brushes. If your powders are more creamy, consider using a makeup sponge or beauty blender instead.

One-sentence summary -- Determine whether you have warm or cool undertones. Choose a contour kit that matches your skin's undertone. Buy the powders separately if you cannot find the right kit. Do not use bronzer or illuminator on your nose. Obtain a selection of clean, natural-hair powder brushes.

Children thrive when they feel secure in their environment and understand what is expected of them. Develop a consistent household structure, clear expectations, and logical consequences if these expectations are not met. Avoid responding to your child's poor attitude with anger. Instead, calmly deliver your request and then disengage. If your child is younger or may place him or herself in a dangerous situation, disengaging may mean selectively ignoring your child's poor behavior while continuing to actively supervise. If your child is older or in safe circumstances, leave the room (always remain within earshot of a young child). While counting to three, five, or ten is often recommended as a tool to redirect a child's behavior, it may provide even greater benefit for a beleaguered parent. Count in your head before responding to your child's frustrating behavior. Doing so gives you a few seconds to regroup and calm your own frayed emotions. Let reality be your child's teacher. Follow through on the consequences you've set for poor behavior. If your child has been told, for example, that if she responds to your requests with sarcasm she cannot attend Friday's football game, hold firm in your resolve. She'll learn that poor behavior has real consequences. Issue reminders -- but hold your child responsible for following through. Developing brains do sometimes forget what they've been asked to do, so plan on allowing some leeway for a reminder or two. You might even try a written reminder. Consider developing a system of "warnings," but follow through with consequences if those warnings aren't heeded. Remember that to attain the long-term goal of a well-behaved child you may have to deal with short-term personal discomfort. You may have heard the adage, "punishing the child punishes the parent," and while you're listening to a temper tantrum or dealing with an angry teenager you'll recognize the truth of this saying. In the end, though, your job as a parent is to struggle through the immediate discomfort of a situation, recognizing the long-term benefits at stake. Children often display poor attitudes and other bad behavior because they feel out of control. Employing a time-out interrupts the cycle of this behavior, giving the child a moment to regroup and reflect. Consider targeting the length of a time-out to the age of your child (for a 2-year-old, for example, set a timer for two minutes). Ensure the privilege withdrawn relates in some way to the poor behavior you're trying to correct. A child who refuses to put down his video game console, for example, may lose the use of this toy for a day. This technique works best as part of a pre-arranged behavior management strategy. Sit down with your children and decide upon behaviors you expect -- and privileges they'll receive in return. For example, you might agree that your child will receive the privilege of watching a favorite television program if she completes her homework without fussing. Creating a system helps children learn that with increased privileges come increased responsibilities.
