When I saw this teddybear mermaid necklace pop up in the Moon Bunny etsy shop, I couldn't resist treating myself. It's a teddybear... and a mermaid. And it has little golden shell nip-covers. How ridiculously, hilariously cute is that!?
It's incredibly well-made as well, with so much attention to detail.
I also made myself a few gold-coloured mermaid accessories recently:
I got this seashell mirror compact on ebay for a couple of quid and glued some swarovskis and plastic shells to it (I got the shells is a mermaid jewellery kit for kids and painted them gold).
A papercraft seahorse I got from Millers and turned into an earring...
... And here's a sparkley stud earring that I made from a gemstone sticker from Paperchase glued onto a piece of clear PVC which I then glued onto an earring back. Cheap as chips!
