Ok so first quilt, do not make the experience about learning frog sewing (rippit rippit!). Finish, wash the heck out of it, and move on to your next one. Maybe try spray basting next time : )
If the quilt stitching really bothers you, make it a wall hanging, where you will never see the back. Or make it a nice dog bed.
Congratulations on completing your first quilt! May there be many more : )
