A Lady and Her Children Relieving a Cottager (1781) by William Redmore Bigg, English, 1755 - 1828Some very interesting hats in general in this painting.
A Market Girl Holding a Mallard Duck (1787) by John Russell, English, 1745-1806
I made my own version with less fullness, and more of bill-shaped brim in some lovely teal silk taffeta I picked up at Affordable Fabrics in Rocky Hill, CT. That place is a treasure, but it's real hit-or-miss as to what gems you can find hidden away on the flat-fold remnants tables. You also really need to know what you're looking for, and have a good handle on how to identify fibers, as nothing is labeled.
A Girl Gathering Filberts (1782) by William Redmore Bigg
This spring-ey little piece is a very similar shape to the ones I have been making. I think I need to re-create one from this portrait with that pink ribbon.
Mrs Ogee, satirical print published by Matthew Darly, 1775
This one features an older lady in a more olive green with blue puffed trim and a wider brim shape.
There is an extremely helpful, extensive list of sources a the Buzz at the Hive. Especially helpful for the American Revolution period. Now, on to cranking out more hats in time for the season before the baby arrives!
