I first really discovered sea pottery on a recent holiday on the Isle of Arran, off Scotland's west coast. One of the first pieces I found was this one, which is now for sale in the Crafty Green Poet Etsy shop, it would make a perfect pendant for a necklace, don't you think?
Since that holiday I've looked for sea pottery and sea glass whenever I've been on a beach. I've found some lovely pieces on the beaches at North Berwick and Musselburgh. Some can be re-purposed just as they are, like the two in the photo below - the smaller one is an ideal size to use as a an incense cone holder. (These two pieces are not for sale, I'm using them myself!)
Other pieces can be used in jewellery, mosaics or assemblages. I'll be adding quite a few pieces to my Etsy shop over the next few months!
It's amazing what you can find on the beach, if you keep your eyes open!
Of course, there's a lot of less appealing things found on beaches, if you're in the UK you can volunteer with the Marine Conservation Society to help keep our beaches clean.
