Dreyer trained as a silversmith at the Georg Jensen Sølvsmedie and was awarded a silver medal for her ""master"" piece in 1996. She also has a degree in jewellery design from the Institute of Precious Metals in Copenhagen. Her hollowware mostly comprises small jugs, bowls and cutlery, and her goal here has been to achieve a simple and unpretentious expression, where the shape underlines the special characteristics of silver. Her jewellery design spans more experimental exhibition projects as well as little series, where form and colour work together to express ornamentation as a symbol, rather than a representative of value. Dreyer’s work has been exhibited at harlottenborgs efterårsudstilling in Copenhagen, and has received several awards, i.a., the Skt. Loye Pris from Kjøbenhavns Guldsmedelaug and Kunsthåndværkerprisen af 1879.
