I decided to try using painters tape to mark the quilting line for some straight line quilting a la Jacquie Gehring…she does this when she wants really straight lines. I usually mark the lines with a Fonds and Porter graphite pencil. I have never had any trouble with it washing out but I hated to use it all over this white sashing. It also doesn’t show up well on black.
I marked the side of the tape I needed to sew. This keeps the space between the two tape lines the same across the quilt.
