I like my stitch length tight. On my machine I set at 1.8 but stitch lengths vary on different machines, I think anyway.
I’m often teased that I trim, just the raw edge at the very edge without taking away the width of the seam allowances, with my pinking shears. Fabrics will fray. I do this because I don’t want someone bringing a quilt back later, for me to repair, because a seam frayed out. I know this takes more time and some may think unnecessary but we all have our own ways of doing things and I learned from a young age to edge finish all seams. As they say, so far we have no quilt police, but the way this world is going, who knows.
Good luck with your quilt. I’m sure it will be fine. Relax and enjoy the story of your quilt. Every quilt has one. Have a nice day-Toogie
