  • Step 1: Good Starting Point for Crafts: Easy Way to Clean Acorns for Decor

    The drying process and baking the acorns in a single layer for 2-3 hours are important steps to help prevent future insect problems. Once they have cooled completely, they'll be ready to enjoy for a long time in projects and seasonal decor.
    Acorns without caps can also be used, adding natural imperfect beauty to your decor. If you find loose acorn caps, let them soak as well. After they dry completely, attach the caps with a small amount of hot glue.
    After collecting the desired amount of acorns, one of the best practices is to soak them in warm soapy water. This is the easiest way to remove dirt and check for any signs of little bugs before preserving them for crafts and decor.
    Fill your kitchen sink, utility sink, large bowl, or large bucket with warm soapy water. Soak acorns for about 30 minutes. Some people recommend half a cup of vinegar, but warm soapy water is the most popular method and has always worked well for us. We've used this process many times, and it works like a charm.

    Cindy's Acorn Tip: I have always collected acorns that are attached to small branches whenever I can find them. Remove the leaves before soaking the branches. If they're higher up on the tree, use a long pole or a strong branch to bring them within reach. Bake the branches along with the acorns. As you will see below, they're another gift from nature and perfect for fall and seasonal decor.
  • Step 2: Drying and Preserving Acorns

    For the drying process, place the clean acorns in a single layer on a cookie sheet or baking sheet. Bake them at 200 degrees for 2-3 hours, leaving the oven door closed. This helps remove moisture, making it the most popular method, and does a great job of removing signs of insects and reducing any future insect problems.
    When the time goes off, remove the baking sheet from the oven and let the acorns cool completely before applying the clear acrylic sealer.
    Cindy's Note: I don't line my baking or cookie sheet with foil for my acorns. Since I have preserved an overabundance of acorns for crafts and seasonal and fall decor over the years, I have never had a problem with sap getting on the pans, and this method works and saves a lot of time.
  • Step 3: Seal Acorns for Lasting Beauty

    Once the acorns have cooled completely, apply a light coat of acrylic sealer. Sealing clean acorns helps protect their natural beauty, so you can enjoy your acorns in craft projects and fall decor for a long time.
    Cindy's Acorn Tip: I use a matte acrylic sealer because it keeps my acorns looking as natural as possible. Mod Podge is my favorite sealer, and I have enjoyed using it for all these years.

    The best practice when storing acorns is to keep them in a cool, dry place.
    Cindy's Note: I have an overabundance of acorns, so I store my acorns in a canvas bag in an airtight container in a closet. Some of these I preserved 20 years ago still look just as beautiful today. That's one of the reasons I love decorating with them; they can be enjoyed for a long time.
    Store them in plastic bags, canvas bags, or an airtight container.
