Combine colors to personalize your palette, such as by adding black to darken a color. A drip painting can be done with only one color. You can also layer multiple colors to create unique effects. How many colors you use is up to you. The colors you choose also depend on your artistic vision. Some colors commonly go well together. Red, yellow, and blue are primary colors that stand out on their own and can be combined into other colors. Colors like yellow, red, orange, and white will give your painting a warmer feel. Colors like blue and purple will give your painting a cooler feel. Water changes the consistency of the paint. You'll need to do this to most paints to help them drip. Add the amount of paint you need to a plastic cup. Slowly pour in water. Mix the paint and add water until it reaches the consistency you desire. More water will thin the color and cause the paint to drip faster. More expensive acrylic paints are paste-like. Mix them with an equal amount of water and a medium such as Golden Clear Tar Gel or Liquitex Pouring Medium. Alternatively, opt for fluid acrylics or add a drop or two of paint thinner. Fluid acrylics pour well enough on their own, but you may thin them out further by mixing them with water. Lean your canvas upright against a stand or wall. For acrylic paints, cotton canvasses are a popular choice. Some artists also choose wood boards or thick paper. Any of these surfaces work well for drip painting. It's also useful to have newspaper, painter's tarp, or other thick material beneath the canvas to catch paint runoff. You may also lay the canvas flat on the ground. Gravity won't cause the paint to drip, but you can practice techniques such as spattering or dripping. Place paint at the top of the area you wish to drip paint. Paintbrushes, turkey basters, or other objects can be used to apply different amounts of paint. You can also squirt or pour paint directly onto the canvas. When the canvas is held upright, the paint will quickly begin to drip. How long you let the paint dry is up to you. To establish a solid color layer, allow the paint to dry completely. If the paint is still wet, new paint will drip down and mix into it. You can even allow the paint to twist by turning the canvas slightly. This is a good way to get unique, organic designs. When you're finished, allow the paint to dry.
Summary: Mix your colors together. Thin the paint with water to dilute it. Set up your canvas. Start painting the top of the canvas. Continue adding colors and let the paint dry.

In one sentence, describe what the following article is about: If you prefer to know exactly what you're spraying on your lawn, you can make your own homemade weed killer. These are safe to be applied around kids and pets, and are less expensive than store-bought weed killers. Varieties of homemade weed killer include: Spraying weeds directly with vinegar. This will kill the weeds, but also any non-weed plants that you happen to spray the vinegar onto. Spraying weeds with a 1:1 mix of vinegar and liquid dish soap. This mixture will also kill all types of plants. If you're concerned about putting chemicals onto your lawn, and prefer not to make your own weed killer, buy an organic killer spray. These are sold in gardening centers and plant nurseries alongside their chemical counterparts. Look for a label that contains the word "organic," or that has been certified organic by an organic registry. These will read "OMNI listed." The downside of most natural weed killers is that they are non-selective. This means that they will kill lawn grass or flowers alongside the weeds. If you want to use an organic weed killer on 2 or 3 small clumps of weeds, you need to keep the weed killer off of the healthy grass. Bend a thin sheet of plastic or cardboard into a cylinder, and place this around the weed. Then spray the organic weed killer as close to the weed as possible, so that it stays contained within the plastic cylinder. You could also cut the top and bottom off of a 2-liter soda bottle and place that over the weeds to contain the spread of the weed killer spray. If your lawn is completely overrun by multiple varieties of weeds, the best approach may simply be to kill all of the plants, grass and weeds alike. In this case, spray an organic killer over a large area of weed-infested lawn. A few days later, you can walk over the lawn and pick out all the dead weeds. You can then reseed the ground so that a healthier and weed-free lawn will grow next year.
Summary: Make your own weed killer using household supplies. Purchase an organic weed killer. Set a protective barrier around the weeds you want to kill. Spray organic killer liberally on your lawn if the weeds have taken over.
