Well I was bored a while back and had some huge acorns on hand from the ranch. I started thinking & decided to try and make a snuff box out of one. I cut the top of acorn off, scrapped out all the nut then lined it with plastic dip. I took a piece of cork and glued to the lid of acorn. Lid actually seals tight. This is my first attempt. This acorn is from last year. I have a few new ones from this year that are a lot bigger but they are not dry enough yet to cut & scrape.
