Hi and welcome from another new quilter!
I took a short beginner course where we quilted via machine. We used special curvy safety pins (made for quilting, the safety pins are bent into peanut shapes) to pin-baste the quilt. They were pinned in places where we would not be stitiching. Then we had a special quilting foot for the sewing machines... and I'm not a machine sewer, so I can't be too detailed here, but there was this trick of pulling up the bobbin thread... best check the tutorials on here.
