Page "Patchwork quilt" Paragraph 5

The quilt is formed of three layers: the patchwork, a layer of insulation wadding ( batting ) and a layer of backing material.

These three layers are stitched together (" quilted "), either by hand or machine.

The quilting can either outline the patchwork motifs, or be a completely independent design.

Additional design options is provided by quilting techniques that alter the texture of the quilt.

These include: trapunto ( where additional batting is stuffed into a descrete section of the quilting ), cording ( where cotton cording or yarn are pulled between quilting lines that form channels ), and stipple quilting ( were dense, closely spaced quilting causes the batting to be more compressed than it is in adjacent areas ).

Another, more casual option is to " tie " the quilt.

Heavy thread or yarn is used to tie all three layers together at points across the surface of the quilt.
