Check the site of Patricia Cummings http://www.quiltersmuse.com/. She generously shared whith us her new book
Redwork Embroidery and Needlework Traditions in Europe and America. It’s a huge source for all who look not only for patterns, but also for some historical and cultural reference.
Patricia published also some other craft books, it’s a lot of reading for free!
Check flowers and butterflies by mangold47. It’s a hudge library of beautiful pictures that you can use as embroidery inspirations or as a base to create color pallettes. It’s amazing, that you can use a simple photo in so many ways, not only as a nice object to watch.
Have a look at a blog In the fold by Amy Munson Bismarck. She’s showing a wonderful collection of arts & crafts vintage runners.
I love the designs from that time, especially by Charles Rennie Macintosh (I had a chance to see the Glasgow School of Arts, it’s a beautful building). What is more interesting for me, his wife, Margaret MacDonald, was a really gifted artist and embroiderer. Check this site to see her embroidered panel.
