Foundation Piecing

In quilting, foundation piecing was originally used to stabilize 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. It is sometimes referred to as English paper piecing because of its popularity in Britain.

Originally pieces of scrap fabric or muslin were used as the foundation. Now, the use of paper, whether tracing paper, freezer paper or some other heavy weight paper, has become very popular for the use as a pattern for in creating quilt blocks that are all the same size, each with precise, sharp points and perfectly matched intersections. In addition, information such as color and fabric choices can be written on the paper foundation in order to facilitate the construction of the piece and leaving lesser room for error while sewing.

With paper piecing, a shorter stitch length (e.g. 12 stitches per inch) is used when sewing the components together which makes it easier to tear away the foundation after the block is completed. Several methods can be used to prepare the design for use on the foundation: tracing, photocopying, computer printing, needle punching, and pre-set designs.

There are three primary techniques used when foundation piecing: top pressed, under pressed and single template piecing. The technique used is dependent upon your preference and the pattern of the design being sewn. However, under pressed piecing allows for greater accuracy because the sewing is done right on the foundation with the fabric underneath, which allows the stitcher to view the marked seam line and sew directly on it.
