The quarter inch seam can be seen on the back of the fabric.
Quilters use a ¼ inch seam allowance unlike most dress maker patterns that require a 5/8” seam allowance. Sewing an accurate ¼ inch seam ensures the patchwork pieces will fit together and the quilt will lie flat. Using tape or seam guides will help with accuracy.

Seams are often pressed in alternate directions in order to reduce bulk and make matching points easier. At times seams are pressed open but this method allows the fibers from the batting to migrate through the openings.
Quilters like to use chain piecing to help with accuracy and to speed up sewing.
