Q&A for How to Dry Acorns for Crafts

Yes, you should give them a quick rinse in a bowl of water. Doing this helps wash off any surface dirt, leaves, or loose debris. However, just rinsing them isn’t enough—there might still be insect larvae inside. After rinsing, lay the acorns out on a baking sheet and put them in the oven at a low temperature, around 200°F, for about 30 minutes. This gentle heat dries them out and kills any hidden bugs, so they’re safe and ready for your project. Remember to let the acorns cool for a bit before using them for your project.

You can use clear acrylic to preserve and protect them.

Yes, if you want them preserved for a longer time period; otherwise, your caps will age and your nuts will not.

Once they are dry, they should last as long as needed, as long as they aren't re-wetted. To further prevent the chance of mold growth (from moist environments), seal the nuts with a craft or wood varnish of your choice.

You could use a butter knife or just take it off with your hands.

I personally have had no problem just keeping the acorns without drying them. Just be sure there is no excessive moisture in the area your are storing them in (a sandwich bag or plastic container will do). Then, just place them outside in the wintertime near a tree or a bird feeder so they can enjoy their own little snack.

Bugs! I once collected a bunch of acorns to fill a clear glass bowl-like container for a beautiful rustic display fir a table at the end of the hall. A few weeks later I found larvae (dead, thankfully) all over the place around the table.
