Following Grandbear’s famous Treetise, she embarked on the most important work of her life, as a Coziness Consultant for dens, nests, burrows, tree-holes, and even pond bottoms. Every fall, she traveled the Ancient Forest from home to home, sticking her nose in rabbit warrens and climbing trees to reach the highest nests, bringing her Cozy Sensibility to every creature in the forest.

Her work includes innovations in nest-weaving (based on her mother's lessons in macrame), a celebration of the (then-controversial) use of candlelight in underground spaces, an observation on ponds as both interior and exterior design, an illustrated essay on the decorative possibilities of forest berries, a theory on the geometry of beehives, an ode to the wondrous architecture of anthills, and so much more.

At the time of her death, she was working on A Study in Cozy, compiling her sacred knowledge on this subject.

This book includes 24 pages of illustrations, maps, real bear hair stitches, cups of tea, forest berries, quilts, and poems! so many poems! to welcome in the winter months.
