The quilt is beautiful and a few puckers never interfered with the warmth of a quilt

Not only the warmth is unaffected, but when I finish a new quilt, I wash it to remove all the starch and Elmer’s school glue that I use for basting it. Cotton shrinks, so most of what you are seeing as “puckers” will probably wash away. Just change direction on each row, use a walking foot, and have fun. When I did a linear quilting on one of my quilts, at the end of each row, I just made my stitch longer and sewed about 1/8” away from the edge so I was sewing the basting for binding around the quilt as I went. Win, win. Two jobs done at once.
