Quilts were almost always made of wool, unless they were remade from bed curtains or quilted petticoats.
However, the idea that all early quilts were made of worn clothing is a myth.
Quilting was done in straight lines, often with double and triple quilting, although flowers, baskets, feathers and wreathes were not uncommon. The dye process was long and involved and colors changed depending on the mordents used.
Home dyes used onionskin, nut shells and bark to create yellows, browns and greens, but they were not used as commonly as myth has it.
Reliable permanent dyes were widely available in the mid 1800's.
Pinks and dark roses were also seen most likely made from a madder dyes. The mid 1800's saw more appliqu quilts being made, with more elaborate quilting.
A side note from The Patchwork Pilgrimage: "Further proof that ornamental patchwork is no newcomer to the church is provided by this fascinating pieced silk chasuble that is believed to have been made around 1540.
During the Reformation, Roman Catholics were driven underground, and in England, persecution was given additional impetus by King Henry VIII's divorce from Catherine of Aragon in 1533, when he broke with Rome and forced his subjects to swear allegiance to himself as the head of the church.
Backings were often of linen, which was considered a utility fabric.
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.
