Foundation piecing Foundation block piecing consists of sewing pieces of fabric on to a paper or a muslin foundation to form a quilt block. Foundation piecing can be used for creating full sized quilt blocks as well. Using the foundation piecing technique to piece blocks allows a quilter to construct complicated patterns easily and accurately .
Make sure to allow plenty of fabric for each piece.
