I tried to add a comment then my smart phone outsmarted me, so I'm very sorry if this a a duplicate response. I tried wavy lines the first time on a grandmother's flower garden that was huge and had taken years. It sat for a couple more years bc I couldn't figure out how to quilt it. I decided on wavy lines, maybe about 20 degrees off, and I made them between a half inch and two inches apart. In a few places, I let them overlap a bit. I was happy with the result, and it was easy. I still use wavy lines but only when it doesn't distract from the piecing. I also use them going in both directions when I have a huge triangular space to fill, like a medallion quilt and the medallion is on point. I learned all of this from Angela's books and videos. She's fantastic ❤ If you're still hesitant, you could try it out on a Linus quilt or other quilt that will be a give-away.

Can you run it parallel to the rollers? That way, you won’t have the length chopped up to fit inside the reach of the machine. 🌷

I practice a new design by cutting open a brown paper shopping bag, taping it on the wall, and then drawing the design over and over again. If you use a sharpie, use two layers. I drew probably two hundred feathers before I figured them out.
