Having spent many years involved in photography, the move to the creation of objects that required a hands on involvement, was a life altering event that opened up a whole new world. Creating sculptural objects, whether in steel, wood, or glass, or a combination of these mediums, required an endless related series of experiments in these materials which she engages in today as she continues to explore these avenues of expression. 
Willi states that her art comes from within, but it is also the result of a variety of life experiences and outside influences. Although some of her glass castings are representational, they are more about  exploration of color, form, and design.  Creating her glass castings and exploring the visual dimension of glass has been an endless  series of ongoing discoveries that fill her life with joy.
