Place your fingers next to the area of skin you're holding the razor against. Then, gently pull the skin upward with your fingers. Each time you move on to a new area on your face or neck, move your free hand to that area and pull the skin taut. Shaving over taut skin will help prevent you from cutting yourself.

Cut the potato through the middle. Do not cut it lengthwise. You should end up with two roughly equal halves with a flat, circular base exposing the potatoes' flesh. This will be the bottom of your potato half. Fill a watertight glass or ceramic container with at least 1 inch (2.54 cm) of warm, fresh water. You want about half of your sweet potato sections to be submerged. Too little water may prevent them from sprouting, while too much could drown out the sprouts. The water should be at or just a little above room temperature. If the water is too hot, it could scald or hurt your sweet potato. Place the exposed flesh of your sweet potatoes down in the water. Try not to overcrowd the container. There should be a little more than a finger width's worth of distance between potatoes to allow the sprouts to grow. Once your sweet potatoes are set up, place the container in a warm area such as a window sill or near a heat vent. The ideal temperature is around 80 F (about 26.5 C) or slightly warmer. If you do not have a consistently warm area, consider investing in a heat lamp to keep your potatoes warm. You can buy one from most home improvement or gardening stores. Check the water levels for your sweet potatoes every day during the 2-3 month sprouting process. If you notice the water levels dropping in your potato container, top it off with some warm, fresh water. Do this only as necessary while your sprouts grow. The exact amount of time you will need to grow your sweet potatoes will depend on a number of factors. After around 2-3 months, though, they should be around 6 in (about 15.25 cm) tall with leaves and roots starting to grow. At this point, they are likely ready to transplant. Use a knife to carefully remove your slip from the sweet potato at the point where the slip meets the tuber. Try to save as much of the root system as you can. At this point, your sweet potato sprouts should be ready to grow.

Being clean will help you look and feel your best in front of the camera. Shampoo and condition your hair and create a lather with your soap or body wash. Go over your whole body with the soap from top to bottom. It's best if you take a shower either the night before or the morning of picture day. It's best for your skin to keep your shower short (5-10 minutes) and the water lukewarm or cooler. Pat yourself dry with a towel and moisturize your body with body lotion afterward. At the very least, comb out any tangles so it looks neat and nice and give yourself a straight part. If you want, straighten, curl, or scrunch your hair to make it look a little more special. Clean your face every night, and if you have a foolproof method that prevents acne for you, follow it. This will improve your chances of having a clean, clear, beautiful face on picture day. Use a gel-based or foamy cleanser if you have normal to oily skin. Use a creamy moisturizing cleanser if you have dry skin. Make sure to floss and brush your teeth every day in the morning and at night. Doing this will remove bacteria from your teeth which will keep them whiter, help prevent gum disease, and keep your teeth from decaying. Make sure to brush for about 2 minutes every time to make your smile look bright. Before taking your picture, you may have some ketchup on your cheek from lunch or some stray hairs sticking up. Pack a comb and hand-held mirror in your backpack the night before so you can give your appearance one last check and touch up before getting in front of the camera. A fresh trim will look great in your school pictures. For a clean-cut, put-together look, get a haircut just a few days or a week before picture day. Make sure you're drinking enough water and getting enough sleep in the days leading up to picture day. Keeping yourself hydrated and well-rested will give you an energized smile and healthy-looking skin.
