One of my all time favorite quilts, a charming, 9 patch top. Blocks are circa 1830/40 but joined together later and fabrics are 1830s and 1840s and earlier, even 1790.
The four corner blocks feature stripes with Prussian blue and the lighter (less often seen) Prussian Green.
And here's another block from the same quilt top with a Prussian blue plaid often called a buff and blue (top right corner).
And this block features dyed indigo fabric with a resisted or bleached diamond design.
More of the top.
