I want the pattern designs on this project to be cohesive with the era Elizabeth and Lily lived in.
What really excited me is the sisters association with William Morris. It was his publishing house Kelmscott Press that directly inspired Elizabeth to start Dun Emer Press. 
The Arts & Crafts movement and Art Nouveau were both making serious shapes in home decor during the late 1800’s. What I love about these two movements is their shared inspiration; the beauty of nature & craftsmanship.
I continued looking in other areas of decorative arts during the late 19th Century and early 20th Century. I collected images of floral motif designs on sites such as Pinterest and discovered an extremely talented illustrator by the name of M.P. Verneuil and a beautifully collaborated book with his peers, The Plant and its ornamental applications, published in 1896. 
I looked through some of my own books such as 4000 Flower and Plant Motifs by Graham L. McCallum, Pattern Sourcebook: round the World; 250 patterns for projects and designs by Shigeki Nakamura and Floriography: An Illustrated Guide to the Victorian Language of Flowers by Jessica Roux. Not to mention a trip to the library is always a fun way to find resources, if you’re a nerd for that kind of thing. I found Spectrum: Heritage Patterns & Colours, a collection of fabrics and wallpapers found at the Victoria & Albert Museum.
