If you are looking for some inspiration, check out the website of Elva Fields.
There are funky large beaded necklaces, one of a kind pieces and my favorites, these up-cycled chunky necklaces, like this “tangled up in gold” necklace, assembled from chains, earrings and a brooch.
Definitely a fun way to revive old pieces and good project if you want to set yourself a treasure hunt at local yard sales and flea markets.
