The felt swan shown here, on display in the Hermitage Museum, dates from the 4th-5th centuries BC. An object made of felt and deer hair with the figure supported by wooden stakes, it was part of a burial mound in the Eastern ranges of the Altai region in Russia. This image is from the book Felt, by Willow G. Mullins, an account of the many uses of felt over spans of centuries to contemporary times. It is an example of a type of book in the library that can serve as good starting points for your imagination, beginning with raw materials.
When experimenting with various types of media and processes associated with them, another type of book that is useful to remember about are the books about art hazards. As many people know from studying art, it's easy to forge ahead and forget that some of the properties of materials may be less than benign for health.
