Singer usually ahd a screw on seam guide too. I have one for my FW from my now dedceased portable
Singer. But to get it to work I put one of those orange plastic strips under the seam guide.
Though I read in Jan Krantz's Hunter Star quilt book and she did show using a double stick tape and a small maybe 3" ruler to the bed of the sewing machine. It is thicker and easily worked with.
I also know of a few people who put a pile of sticky noted for their seam guide or moleskin. Neither of t hose worked for me.
I do use my 1/4" flange seam guide foot a lot. But i hold my material differently such that i can't really describe it and it works. Sorry am in hospital so no way to get you a picture for a while.
