Oh, of course! Let's say you'd like to fill a space with a grid of sewn lines an inch apart from each other. Stick down your first length of 1" masking tape either along a seam edge or through the center of the open space. I'm not too precise about these things, no quilt police hang around me. (But some folk measure for exactness, I hear :lol: ! And many prefer to stitch from the center out to the edge to ensure flatness.) Begin by quilting right up along the edge of that tape, both sides if need be. Remove the tape. Now restick it along the line you just quilted, using it as a guide and off you sew again! When your space is filled with 1" sewn parallel lines, start placing the tape the opposite way. I hear there are quilters out there who make neat little intersections where the sewing lines meet, but that's not me either!!! It's easier to show this than it is to describe it, but give it a try and let me know what happens, OK?
