In one sentence, describe what the following article is about: After you've done all the work to establish the correct blind widths, don't forget about measuring your windows from top to bottom as well! Measure each window from top to bottom at the center, left side, and right side, and use the longest measurement as your guide. If necessary, order blinds that are slightly longer than this in length for instance, if your measurement is 67 cm and your can only order either 65 cm or 70 cm, go with 70 cm. Before attaching the brackets to the window frame, clip them onto the ends of the roller blind and hold it up in position over the window. Make sure it fits according to the existing spacing and/or the markings you made while measuring or cut blinds to fit properly. Installing roller blinds will vary based on the specific design and manufacturer, so follow the instructions that come with your blinds. However, there are some universal recommendations to follow: Hold each bracket in position and mark the screw holes on the window frame. Use a bar/spirit level (and a string if necessary) to make sure your bracket markings are level before drilling. Pre-drill holes for your screws, and use anchors if you aren't drilling into a solid, sturdy surface. After you screw the brackets into place and slide the blinds onto the brackets, tug on them to make sure they are securely attached.
Summary: Measure for length before ordering or buying blinds. Test-fit the blinds before installing them. Mark, level, pre-drill, and attach the brackets, then add the blinds.

Do not put off studying until the last minute. If you hold off until the night before or, even worse, that morning, you are less likely to retain all of the material because of stress.

Try to find a place free of distractions, like your phone, television, and people who might bother you while you're trying to work. You want a place where you can focus! It also helps if your study spot is comfortable, but not so comfortable you'll want to relax instead of work. Look for a place with a good seat and a table to work at. You could try studying in a library, study hall, cafe, or even your kitchen if its not too noisy. Team up with someone who's in your class or preparing for the same test. You can quiz each other as you study, and help explain things to each other if there's a part you don't understand. However, remember not to choose a friend who will goof around instead of help you study! You could also form a study group of several people. If you can't find anyone from your class to pair up with, ask a family member or other friend to quiz you. You could also try to study with someone who has the same teacher during a different period. in class. Paying attention to the teacher will improve your understanding. Make sure to ask any questions you may have during your class. Don't start snoozing--you wouldn't want to miss it when your instructor starts talking about what will be on the test! Taking notes during class. Put away your phone and any other distractions. Participate in class, if your teacher gives you the chance to ask questions or make comments. Some may be assigned or in the textbook or on the textbook website. Your teacher may have others. Ask them about study guides and practice tests!

Problem: Article: These handheld tools allow you to reach right against the edge of the wall. If using an orbital sander, you probably already reached the walls. In this case, you can skip this section, and remove the finish at the corners with any handheld sander. For this small remaining area, you may be able to skip some of the steps you used on the whole floor. That said, you will need to start with a coarse grit to remove the old finish. Move the edge sander back and forth along the wall in small triangular movements. This is less likely to leave marks than a side-to-side motion. Most tools are designed so moving right (clockwise) along the wall is easier than the other direction. You can now skip straight to 80-grit sandpaper. Sand carefully until the edge matches the rest of the floor. If you want to finish with 100-grit sandpaper, you'll need special techniques to avoid burning the floor and paper. You'll need a sander with a slow speed setting, and preferably an "open coat" sandpaper. Your floor is now ready to be stained and/or waxed. Try to keep dirt, abrasives, and heavy objects off the floor until it is finished.
Summary:
Use an edge sander. Start with 36-grit. Sand in a clockwise zigzag pattern. Repeat with finer sandpaper. Vacuum up the dust.
