Birdsall's pieces take much time and patience, as all are subject to meticulous hand cutting on the exterior and detailed rim. Acid polishing softens the cut surface creating a contrast with the glossy interior of each piece.
Birdsall’s work has been shown extensively throughout Europe, the UK and the USA. From a staggering 400 international applicants she was selected in 2009 to exhibit at the Hawk Galleries, Ohio, as part of B.I.G.G: Breakthrough Ideas in Global Glass and in 2014 she took part in the prestigious Coberg Glass Prize. She has work in the permanent collections of the European Museum of Modern Glass.
