It takes a little time but makes paper removal a snap. You can get her Oct BOM online for free for a good tutorial.
I found that for me, the creasing and sewing with shorter stitch length helps the paper come out just fine. I did that once and found for me, it takes way too time, with the same results. I know some who do the sewing, but once they pre-crease (in both directions) they find it works just as well. Of course, there are many ways to do it. :0)
