Place the parchment paper over the jug, and gently press the hot iron on top, moving it in circular motions. The heat will help the paste adhere to the plastic and create a textured finish.
Continue the process over the entire surface of each jug, reapplying the paste as needed.
Let the planters cool completely before use.
Once cooled, fill with soil and your choice of plants.
For a different look, consider adding a few drops of paint to the baking soda paste to create colored planters. You can also experiment with different textures by varying the amount of baking soda in the paste or using other pantry items like cornstarch for a finer finish. If you want a more rustic look, lightly sand the surface before applying the paste, or use a sponge to create a stippled texture. Remember to let your creativity guide you in customizing your planters to suit your personal style.
