English Paper Piecing (EPP) is technique of sewing patchwork quilts by hand. It involves using paper templates to act as a stabilising layer when sewing pieces together for accurate results. Fabric is wrapped around the paper template and then the finished shapes are whip-stitched (previously known as over-sewing) along the edges to form the quilt.
