Paint a Mural
Sure, flowers are colorful, but if you want to make a real splash, paint a mural. Murals are making a comeback in public spaces and can be an exciting addition to the look and feel of your park. You can take a creative license with this project, but you don't want the mural to look like graffiti. So, start with a theme and a careful plan for your project.
Once you've got a plan, decide on your canvas. Whether it's a wooden fence, cement wall or even a brick walkway, clean the area first. This will ensure that the paint will stick well. It also doesn't hurt to prime the area with a base coat. Acrylic paint is one of the most durable and long-lasting types for this kind of project -- and you'll want your hard work to withstand the elements!
Next, you'll outline your mural. You can be as detailed as you like, but at least sketch where certain elements of the design will go. Then, start painting.
