Problem: Article: Choose a representative area of the concrete, hold the #9 pick like a pencil, and apply the same pressure you would to draw a roughly 2in (5.1cm) pencil line on the concrete. Look and feel for a scratch. Keep working your way down the pick numbers (#8, #7, etc.) until you reach a pick that doesn't leave a scratch. If, for example, the #7 pick scratches the concrete but the #6 pick doesn't, estimate that the concrete has a MOHS (Measurement of Hardness Scale) rating of 6.5. The higher the number, the harder the concrete. Buy a set of MOHS hardness picks online or at a home center. When you go to rent a concrete grinder, the set of grinding discs that you rent with it may vary based on whether your concrete is soft (5.5 or lower), medium (6.5), or hard (7.5 or higher). Look for concrete grinders to rent at hardware stores and tool rental retailers. The set of concrete grinding discs that come with the grinder should range from about 40-grit to 3000-grit. If given the option, choose a set of grinding discs that specifically suits either soft, medium, or hard concrete (based on your MOHS testing). You must use a specialized tool to grind concrete; a standard sander won't do the job. The grinding discs must be metal-bonded diamond discs. Non-diamond discs aren't hard enough to grind down the concrete properly. Before agreeing to rent the grinder, make sure that it feels comfortable enough for you to use. Get instructions on how it works, and ask if you can start it up, if possible. Renting a grinder can cost as much as $1000 USD per week, so this project may not be especially cost-effective if you're only working with a small concrete surface. It may actually be cheaper to hire a pro to do the job. Wear a dust mask, thick gloves, safety goggles, and ear plugs. The grinder is loud, creates a lot of dust, and can cause serious injury if used improperly. Therefore, consider the user's manual to be another piece of required safety equipment. Wear work shoes with a good grip. No-slip footwear can help prevent accidents caused by sliding, slipping, or falling over. If you are working in an area currently undergoing other construction, wear a safety helmet. In fact, you may want to wear a helmet in any case. Attach the disc according to the grinder's instructions. To remove sealer, stain, or other contaminants that wouldn't wash off, start with a 40-grit grinding disc. Otherwise, use the 80-grit disc. Turn on the grinder and use the handle to turn the disc back and forth in half circles while slowly moving forward. Go slowly and work over the surface evenly. Start from one corner of the surface and work your way out and over to the opposite corner. Remember that lower grit values indicate coarser discs. In other words, 40-grit discs are coarser than 80-grit discs. Rely on the product instructions for specific guidance on using your chosen grinder. Pass over the concrete with each disc in your set. For example, go through the following progression: 40-grit, 80-grit, 150-grit, 200-grit, and 400-grit. Pass over the entire surface with each new disc, working perpendicular to your last passin other words, start at an adjacent, not opposite, corner, based on where you started the previous pass. For example, visualize a square concrete surface from above. If you made the first pass from the top left to the bottom right corner, make the second pass from the top right to the bottom left corner. Each pass with a new disc will buff away the scratches created during the previous pass, and in turn create finer scratches to be buffed away by the next pass. Apply the densifier, a liquid chemical hardener, over the entire surface according to the product instructions. Spraying it on makes the concrete less permeable and less likely to form powdery dust on its surface. The best time to densify the surface depends on the hardness of the concrete, as per the results of the MOHS test you conducted. For soft concrete, apply the densifier after using the 80-grit disc. For medium concrete, use it after the 200-grit pass. For hard concrete, wait until after the 400-grit pass. To apply most brands of densifier, pour the product into a small sprayer. Use the nozzle of the sprayer to coat the entire concrete surface, then let it dry before continuing. Work over the entire concrete surface as before, moving from one corner to the diagonally opposite one. The grit on this disc is so fine that it will actually begin the process of polishing the surface. You can skip straight to polishing if you wish, but using the 3000-grit disc will give the finished concrete more of a high-gloss appearance. Grinding concrete produces plenty of dust and debris. After you finish the last pass with a grinding disc, suck up as much material as possible with a wet-dry vac. Some concrete grinders come with an integrated vacuum, which you should definitely use while grinding. Even in this case, though, use a wet-dry vac when you're done grinding. Vacuuming the surface between disc passes is fine but not typically necessary. One thorough vacuuming before you buff the concrete should suffice.
Summary: Test the concrete with MOHS hardness picks before renting a grinder. Rent a concrete grinder with a set of metal-bonded diamond discs. Put on protective gear before handling the grinder. Grind the surface in half-circle motions with a 40- or 80-grit disc. Repeat the grinding process using 80-grit through 400-grit discs. Spray on a densifier after the 80-, 200-, or 400-grit grinding pass. Make the final grinding pass with the 3000-grit disc. Vacuum all dust and debris off the concrete surface.

Problem: Article: You will need tissue paper, your gift, a gift bag, any embellishments, your card and gift tag. You will need several sheets of white paper to wrap around the gift first, then colored tissue to line the gift bag. You will need several colors of tissue paper that complement the color of the gift bag. Colored tissue paper makes a gift more festive! Make sure your gift bag is appropriate for the occasion. If you are going to curl ribbon to add as a decoration, you will need scissors to curl ribbon. Alternatively, you can use pre-curled ribbon or a pre-made bow. Overlap each of the them several inches, alternating colors. Use more or less paper depending on the size of the gift and gift bag. If the gift is small, use half sheets of paper.
Summary:
Gather your materials. Place 3 or 4 sheets of tissue paper on a flat surface.
