Problem: Article: Mow the Bermuda grass down close to the ground, or pull out small sections by hand. Doing away with the bulk of the grass slows its growth considerably, giving the landscaping fabric the time it needs to be effective. Shorter grass is less likely to cause uneven bunching beneath the fabric, as well. Unroll the sheet and stretch it out over the part of your lawn or flowerbed where growth is heaviest. Make sure the sheet is lying smooth and flat. Landscaping fabric is the best ground cover option for broad areas where Bermuda grass is coming in thick. Cut the sheet as needed to fit better over narrow or oddly-shaped areas. Be careful not to tear, wrinkle, or damage the landscaping fabric in any way while you're handling it. Use a pair of scissors or a utility knife to open up the fabric enough to accommodate whatever you may already have growing. If you think you might want to add new plants in the future, wait until you're actually ready to plant to make holes for them. This reduces the number of places where new grass might come up. Don't make the holes any bigger than they need to be to fit around your plants. If you do, you may soon discover that new Bermuda grass has sprouted in the intervening space. Only cut holes for shrubs and other perennials. Caring for annuals forces you to remove the landscaping fabric too frequently. Spread the mulch 46 inches (1015cm) thick. This should be deep enough to allow you to plant new additions later. Leave 23 inches (5.17.6cm) around the base of your plants to avoid crowding the roots and stem structures. Select a mulch mixture that contains the moisture and nutrients your existing plants need to flourish. The dense material will stifle the underlying root growth within about 6-8 weeks. In the meantime, keep an eye on the edges and openings to make sure no new grass has found its way through. Strip any stray leaves you happen to come across manually. Landscaping fabric is a quicker alternative to cardboard-and-mulch ground cover. However, it can create more opportunities for stubborn grass to continue spreading if not correctly installed and maintained. You should not plant a lawn over landscaping fabric.
Summary: Remove as much grass as you can. Place a sheet of landscaping fabric over the affected area. Cut holes in the landscaping fabric to make room for your plants. Cover the landscaping fabric with a layer of mulch. Inspect the area around the fabric periodically for new grass.

Problem: Article: Stuff sacks are a popular gear item used to help keep backpacks organized. They're lightweight but durable sacks that come in really handy for keeping your food items separate from the rest of your pack. Many people fill one stuff sack with food they're not going to eat on the trail, and another one with toiletries. You could use stuff sacks to pack nearly anything, but seasoned hikers don't bother putting clothing into stuff sacks, since packing softer, flexible items around the heavier, more awkward items is a more efficient use of space. Bear canisters are smell-tight containers used to store food, deodorant, sunscreen, and other items that attract bears. They're mandatory to use in certain areas with high concentrations of bears. If you're hiking in a place that requires the use of bear canisters, it's important to pack your canister efficiently so it doesn't become an awkwardly-weighted item in your pack. Don't use any items like clothes to fill the voids in a bear canister. You might use for example rain clothes or pack cover to fill up the space, but not anything that you are going to wear in camp. You do not want any bear attracting smells in your tent, like clothes that have been soaking in food scent an entire day. The canister is likely to be heavy, so pack it as a heavy item between your shoulder blades and right next to your spine. Pack a flexible item like a tarp or extra clothing around the canister so it doesn't move while you walk. This is a convenient and lightweight item that could save your backpack from getting soaked by rain or snow. It's a cover you attach over your backpack in inclement weather. When it's not raining or snowing, the packover is small and light enough to stuff into the top of your pack so you can easily access it when you need it.
Summary: Use stuff sacks to pack your food, but not your softer items. Pack bear canisters efficiently. Get a pack cover to protect your backpack.

Problem: Article: A degreasing solution is recommended for oily or heavily handled silver. If there is oxidization on the surface, you may need to place the silver in a pickle solution before soldering. Optionally, you may use 1000 grit sandpaper to make a rougher surface for joining. Prepare the flux according to instructions on the packaging, if it is not ready to use. Use a small paintbrush to apply this flux onto the silver object(s). Some people apply flux only where the solder will be present, in order to limit the amount of solder that flows to the wrong place. Others prefer to apply the flux over a larger area to minimize the risk of fire damage, but this is not recommended for beginners. Using a small amount of flux in a separate container is recommended, as repeatedly dipping a brush into the original bottle may add dirt and affect its function. Lay the two components next to each other on the soldering brick. Position them exactly as you want them to be joined, noting that they must be physically touching to be joined properly. Use a pair of tweezers to pick up a solder chip and gently place it on one end of the crack or gap to be joined. Once melted, the solder will be drawn by the heat anywhere flux was applied, so you do not need to cover the entire length of the gap. Light your torch and adjust the heat to its highest setting. Begin by holding the torch about 4 inches (10 cm) away from the joint, moving it constantly in small circles to ensure even heating of all components. Slowly move the flame closer to the joint, focusing on the metal objects near the solder, not the solder itself. When the solder reaches its melting point, it will quickly melt and be pulled onto the fluxed areas of the silver. If one of the objects to be joined is thicker than the other, heat the thicker object from the back until the solder starts to melt, then heat the thin object briefly. Use tweezers if necessary to hold the objects in place, but place them on the far end of the silver, away from the flame. You may need to hold down small, thin areas of the silver to provide a heat sink, preventing the thin area from melting. Let the object cool for a minute, then cool it further by dipping it into a water bath. The "pickle" solution described in the work area section is an acidic bath used to clean the jewelry after soldering. Lower the silver into this bath using copper tongs, and leave it for a few minutes to remove the flux and oxidization. Avoid all contact with your skin, clothing, or steel tools, as the pickle bath can be corrosive. Rinse the newly joined silver with water. Pat dry with a clean cloth. If the process was completed correctly, the silver should remain joined permanently.
Summary:
Clean the silver. Apply flux to the joint. Position your silver components to be joined. Position the solder onto the joint. Heat the objects until the solder melts. Dip the object in water, then immerse it in a pickle solution. Rinse the silver.
