Foundation Piecing & Paper Piecing
In patchwork, Foundation Piecing was originally a method used to stabilise pieces of fabric that were stitched together. It first became popular in the 18th and 19th centuries in England, although a 15th-century Italian piece, the Impruneta cushion owned by Antonio degli Agli, may have used foundation piecing. A similar process popular in Britain is English paper piecing.
English Paper Piecing is a pure hand-sewing method used in traditional patchwork and quilting. Foundation Paper Piecing on the other hand is generally done by sewing machine.
