Start with either a plain rectangular doormat, like this Eco Living Natural Coco Coir Mat, or something with a unique shape, like this Calloway Mills Half Circle Natural Coir Doormat. If using, place your stencil on top and tape down the borders with masking tape to prevent it from shifting while you're working. Alternatively, you can hand-paint your doormat with little flowers, birds, bugs, calligraphy text, or any other spring-inspired designs. When you're satisfied with the results, give your doormat a light misting with Flex Seal Clear Spray or another waterproof sealer to protect the design. Finally, style your new doormat for all to see; it'll look brilliant beside some fast growing spring flowers that grow a colorful garden in no time.
