It took me forever to make a quilt this way and then the quilt felt 'hard' full of bulky seams. Some of my guild members like making quilts this way though. You'll have to make one and see for yourself. I would use very thin batting. I'm glad I learned how to make a quilt this way as it does save time with smaller projects.
She was on Nancy Notions tv show showing how to do make the quilt. I remember watching it online for free. It may still be on you tube.
