Every work is crafted from archival cotton paper that prevents yellowing and fading. Nicholls uses minuscule amounts of glue to secure the individual pieces, employing knives and texturing tools to precisely sculpt each delicate part. For the artist, crafting fur and feathers are equally challenging, and how long a piece will take is difficult to predict. He shares:
The largest sculptures I’ve done require several hundreds of hours while the more modest pieces keep me busy for two or more weeks. Familiarity with the subject is a big factor as well. My love of birds often propels me through pieces much faster than when sculpting subjects with (an) emphasis on musculature and structure.
Nicholls’s fascination with paper as a medium stems from graphic design classes in college, in addition to later collaborations with a colleague. These experiences further forged his interest in experimenting with various materials and papers that he had become familiar with through the graphics trade.
