An easy rug to make using a plastic rug grid that can be purchased at any craft store or online plus a few colorful pom poms. You can purchase pom poms or make them yourself depending on how quickly you want to complete this project. If you need something to do with all your leftover yarn this will make a terrific project for a kids room or playroom! Cut your rug grid into a circle or make it in different sizes or shapes for different areas of the home! Alternate pom pom sizes to make an unique pattern.
Once you have all the colorful pom poms made just tie them to your rug grid.
Here are some helpful links to get your started.
One method I found was to use indoor/outdoor upholstery fabric instead of the rug grid to create a rug base and attach pom poms to. View how here..
