My current book from Leisure Arts, Formal Jewelry has you
covered for beautiful crochet beaded jewelry. The pieces in the book are made using not yarn and not wire but gold and silver embroidery thread and black and silver elastic cord.
The necklace below is made with silver elastic cord and sparkling beads for the evening of dancing.
Below are Black Barefoot Sandals perfect for the beach or pool on prom weekend. I grew up in NJ and it's all about the shore on prom weekend...These give you style without wearing shoes. There are two styles of barefoot sandals in Formal Jewelry.
Of course everything in the book would work for weddings and other dressy occasions too.
