A bonnet question

Do any of you know of any good books which shows bonnets from the 1850s and 60s? They are so small in the brim that it is very hard to find out from photos and fashion plates how they really look, even harder how they are made. Especially since they are usually pictured from the front.
If not, does anyone know of any patterns for them?
Book recommendations on mid 19th century fashion are also very welcome.

Apart from that it's snowing outside and we had a snowstorm yesterday. This means that my husband is staying home with me watching the soccer game on TV instead of live. I am currently sewing on my linen chainse to wear with my new bliaut. It will have pleated gores at the side, like the alb that's at the Abegg foundation. Not as prettily smocked though, since I've never done any smocking. I'm also getting close to finishing my second ball of yarn for my shawl which means that I've done half of it. Hooray!

A wonderful book

If any of you who are doing 19th century costumes haven't read it already I want to recommend the book Dressed for the photographer. Ordinary Americans and fashion 1840-1900. It is a wonderful, wonderful book that gives you the chance to see how the clothes on the fashion plates actually looked on real people and how people of more modest means dressed, while still being fashionable. And Jennifer, you might want to look especially at page 434 and 485.
