You should put together some small practice pieces & do a lot of practicing Before attempting to quilt your ( real) quilt. Walking foot for straight line quilting * stitch in ditch, cross hatch, gentle curves*
Hopping foot for free motion. Both take some practice. Walking foot works with your feed dogs, free motion quilting is done with feed dogs down so you can ( freely) control moving the fabric.
There are many utube videos, tutorials to watch, help you see the process.
