Trapunto (stuffed work) quilts were made until the 1840's when their popularity waned.
Early 1800's quilts were usually large (120 X 120), and often whole cloth quilts, or quilts of whole panels, such as the Tree of Life. Sometimes you would find quilts made of plain blocks (such as a simple Ohio star or nine patch) alternating with a plain block.
Quilts and quilt making are a reflection of the life and times of the women who made quilts.
