We follow the evolution of the infrared excess and the dust shell of
Sakurai's Object by considering the results of modelling the dust
emission. The optical depth, grain size, dust temperature, and shell
thickness parameters from the models are discussed. Fits of DUSTY
models to 1-5
m spectra between May 1999 and April 2000 are used to
illustrate the continuing evolution of the dust. The size of the
infrared emitting region continues to grow and may now be big enough
to resolve. This may help to answer some questions such as whether the
dust shell is `blobby' or smooth.
