We probably have millions of acorns in our yard - no joke! They are literally everywhere and you can't take non-crunchy step right now. So a few weeks ago I decided to at least clean off our walkways and deck and when I was finished, I had a good-sized pile of acorns.
Gather your acorns and give them a good rinse, towel dry, then bake in a 170-degree oven for about 30 minutes. This will rid you of any little bugs that may have moved in.
Once they cool, it's time to crack the shells. A small hammer worked well for me.
You can throw away the insides, or save them to feed to the squirrels - and yes, some people even eat them, though I've heard they're quite bitter.
Once you have a nice supply of shells, put them into a plastic zip-top bag and use a rolling pin (or anything similar) to crunch them up into smaller pieces
Give your pot a good layer of Mod-Podge.....
then sprinkle on the crushed acorns. Press them down a little, and shake off any excess. I also used a few caps along the rim to vary the look.
When it's covered and dry, spread another layer of Mod-Podge over the top to seal the shells, and let it dry.
You can leave it natural or spray paint it to match your decor. I'm a painter, so I chose the paint route
