How can I display small seashells I collected from vacation?

You could make a seashell crown https://familyfocusblog.com/diy-crown-made-with-glue-gun-and-wire/ or seashell frame https://www.hometalk.com/diy/decorate/walls/old-belt-seashell-frames-34690135

Old Belt & Seashell Frames

You have options!

You can just find a pretty glass jar or bowl and display them that way. You can make seashell art or crafts. I have done both. I have hundreds of shells. I also use them as a soil topper in my potted plants.

There are many ideas on how to display. Here are a few. Good luck. That will be a fun project! I have mine in antique glass canning jars that I display them in. They are really pretty and simple that way too.
