I have some Glow Line tape but the thing I disliked was that when I removed the tape from the ruler the sticky stayed and only the colored part came off. It was a pain to remove the residue but I finally got it off. I have 3 widths of the blue painters tape and use it a lot. Sometimes I stack layers of it so I can feel a ridge to use as a seam guide. Anlother thing I save and comes in handy is those magnetic cards that come in the mail. I use them on my old vintage machines for a quarter inch marker.
