Should interfacing be used no matter what type of fabric that you use for a quilt?

As nearly as I know, most quilters rarely use interfacing when they quilt. They don't like the way the interfacing changes the "hand" of the fabric and it can add extra bulk. There are exceptions depending on the style, fabric and type of piecing and whether or not applique is involved. Most designs that are machine embroidered need to have a stabilizer while the fabric is being embroidered but the quilter has a choice in leaving some types in or removing it after the embroidery is completed. There are quilt "kits" with a grid printed on an interfacing type fabric so that one places their cut pieces of fabric along the guide lines and then sews them down. It's fast and accurate for beginners. It is similar to paper piecing where the fabric is literally sewn down onto paper. There is now a new dissolving "paper" that can be used which washes out after the quilt is finished. Some antique quilts still have the paper left in them.
