A simple way to add paint color to a rug is to paint a simple border. Use painter's tape to outline the border on the rug, and paint in the area in an accent color. You can paint along the edges and leave the center of the rug in its original color, or you can paint the center of the rug and leave the border the original color. Painting a border is not limited to one row of paint. You can make several rows and incorporate floral or other decorative designs into the border using stencils.
Paint a rug with an abstract design. If you draw your inspiration from an existing room accent, such as colorful throw pillows or artwork, don't fear outlining its pattern onto the rug before painting it in. If this design is from a freestyle concept, take your time and fill in as much color as you want on your painted rug. Some simple abstract rug painting ideas are to paint larger, colorful dots lined up in even rows. Intertwining swirls of two or more complementary colors works in a room that has curved architectural or furniture features.
Incorporating geometric designs on the painted rugs takes a little bit more work. Accurate measurements and taping off the design require some time for this project. A time-saving alternative is to print a geometric design on a large poster paper. From there, you can cut out the lines and use it as a large template for rug painting.
A rug is an accent piece that anchors a room by adding dimension and contrasting textures to the floor, which means that you can do to the rug what you may not want to do to your walls. Work with color tones that work well in your space. Bright and bold colors work in a room with bright and bold accents, and muted colors work in formal living and dining areas.
