I have recently been drooling over embroidery necklaces and you can get the cutest little embroidery hoops by a company called Dandelyne. They are based in Australia and a bit too expensive for me. I did a bit of research and found a couple of great companies on etsy U.K. who make a similar product.
Here are a couple of necklaces *currently available* at my etsy shop, Melted Marshmallow. They are completely hand embroidered by me using quality anchor embroidery threads and 100% cotton.
