Have you ever tried folding the paper on the line and sewing beside the fold? this is the way i do all my paper peicing and it works great, i dont have to remove paper ever and if it is an expensive pattern than it saves the foundations so i can use them again latter for another quilt without violating copyright or spending more money. if it is a large foundation i secure the fabric to the paper in a few places with fabric safe glue but that is way easyer to remove than pulling paper out of the seams. Hope this helps.
