In one sentence, describe what the following article is about: There are several things you will need to help you draw a sphere with this method, so be sure to have everything within reach. Sketch pad or paper Pencil Egg cup Ruler Blending tool, cotton ball, or tissue Keep it close to the middle of the page, if possible, to give yourself enough room on all sides. Remember that one side of your sphere will have the core shadow, which is the darkest part of the sphere, where the light source cannot reach. When you lift the egg cup, you should be left with a perfect circle on your paper. Your light source will come from either the top left or the top right. The opposite side of the light source is where the core shadow will be. For a shadow that emerges from the left side of the sphere, your light source should be in the top right corner. Conversely, for a shadow that emerges from the right side of the sphere, the light source should be in the top left corner. Lightly mark a point when you reach the 1 centimeter mark. Then, draw an arrow in the corner down toward the circle, showing the direction of the light. That point is the center of the highlight, meaning that the interior of the oval will not be shaded later. This refers to the bottom edge of the circle opposite from the light source. Aim to leave about centimeter between the original circle and the edge of your egg cup. The space you just created will be part of the core shadow of the sphere, the darkest part where the light source cannot reach. The shape can be described as an eclipse. Keep this in mind as you read further instructions. You should now have four eclipses, made by the egg cup, on the bottom edge of the circle opposite the light source. These eclipses should take up approximately half of the circle. They will be used for mid-tone, or gradual shading of the sphere to help give it its 3D appearance. At this point, the egg cup is too big to make smaller mid-tone outlines. Lightly draw them in freehand form, using the shape of the small oval (i.e. the highlight spot) and expanding outward until you have three increasingly large ovals. It is acceptable to leave a gap between the largest oval and the middle-most eclipse from the egg cup. This is the eclipse that is dedicated to being part of the core shadow, so it needs to be dark as you can get it with your pencil. As you work your way upward, toward the highlight oval, each eclipse should be somewhat lighter than the next. When you get to the highlight spot, it should be completely untouched. Work your way over the whole sphere, gently blending the different shading tones together so that they seamlessly taper from light to dark. Work from the lightest partthe highlight spotto the darkest part to avoid pulling led from darker areas into lighter ones.
Summary: Prepare your materials on your desk or table. Place your egg cup upside-down on the paper. Trace the outline of the egg cup with a light line. Decide the direction of the your light source. Mark a light guideline, with a ruler, from your light source to a spot about 1 centimeter inside the circle. Draw a small oval shape around the point you just made 1 centimeter inside the circle. Place your egg cup over the circle so that the opposite edge of the light source can just be seen. Trace the curved edge of your egg cup from one side to the other in a light outline. Repeat Steps 7 and 8 above, moving closer to the middle of the circle, three more times. Freehand a few more mid-tone outlines on the side of the circle close to the light source. Shade the bottom-most eclipse as darkly as possible. Shade the proceeding eclipses gradually lighter shades. Blend the tones together with a blending tool, a cotton ball, or a tissue.

In one sentence, describe what the following article is about: Many personal finance magazines and blogs on travel hacks have articles that compare the frequent flyer mile programs of the major airlines. You'll want to look for which programs give you the most miles per dollar, which ones allow you to exchange points from other affinity programs for miles, and other terms of the programs. Some rewards programs offer higher points-for-miles exchange rates than others. Others offer better selections of vacation packages. But some cards only work with a limited number of airlines. Make sure that your choice of frequent flyer program is aligned with any rewards programs you are already enrolled in. Enrolling is usually as simple as going on the website of the airline carrier, creating a frequent flyer rewards account, and agreeing to abide by the terms and conditions of the frequent flyer miles program. Some companies have prohibitions against this, but many companies, especially smaller ones, do not. If you work for a company that lets you take advantage of those miles, ask the appropriate staff person to start booking your business flights on the airline where you have your frequent flyer miles program set up. Make sure to check with a tax professional to determine any tax-related liabilities you may incur if you receive frequent flyer miles from employer-paid business travel. You'll want to carefully look at what kinds of exchanges will get you what you want. For example, you may be able to earn an all-inclusive destination vacation package in a shorter period then it would take you to accumulate the miles necessary for airfare to the same vacation spot. Make sure you look at the rewards offered by both points and miles and assess both in terms of dollars and time spent to earn the trips you want.
Summary:
Research airlines for the best frequent flyer miles programs. Assess which credit card rewards programs you're enrolled in work with which frequent flyer miles programs. Enroll in the frequent flyer programs that interest you. Check if your company will give you frequent flyer miles from business travel. Exchange miles-for-points or points-for-miles to earn the trips you want.
