Marking is the practice of using utensils such as fabric mechanical pencils, washable pens, air soluble pens, chalk, etc. to mark the lines on which the quilter will cut or stitch. Marking can be used before cutting fabric for piecing patterns or before stitching seams, cross-hatching, or free-motion quilting patterns. Marking technique may vary from quilter to quilter as it simply serves as a guide to keep the quilter’s work tidy and accurate.
