I am posting for the first time and am making for the first time some (hopefully) quilted place mats, wanted to start small. I want to quilt them in diagonal straight lines about 1.5 in apart going in both directions. I have just a domestic machine and want to know if there is a way to keep the lines straight and consistent in some way other that drawing lines on the fabric to follow. Somewhat garbles sentence but hope you understand what I mean,I would be flapping my hands around as I talked if you could see me! Thanks for any help.
