I'm new to anything other than SID. I have discovered painter's tape in different widths helps as a guide--but don't sew over the tape (didn't know my first time
). My machine has a serpentine stitch that I recently fell in love with. It is an automated stitch meant for darning on my old Bernina. I use stitch width 2 of 4 and length is the same, 2 of 4. It makes a nice gentle wave.
I have used the washable markers to draw stitching lines with my rulers. They didn't come with instructions, so I searched youtube for videos. I like one ruler that makes a spiral pattern...

I used it in the corner on last quilt.
Here's a pic of serpentine and a spiral that I've done. I will also follow lines in the fabric.
