Usually I approach a series in one of two ways:
1. Start 4-12 pieces at the same time, then work back and forth on the pieces until all are completed. With this approach, the pieces are usually all the same dimensions and medium. I like the feeling of continuity that results naturally from working on the whole series at once.
2. Establish a title for a series, and then add pieces to the series over time, as new work is completed. With this approach pieces are often a variety of both sizes and medium.
I enjoy the ease of titling with a series……Vista 1, Vista 2, etc.
Strata (variety of sizes and media)
Vital Forms (variety of sizes and media)
