I have noticed a few questions coming up lately about how to do "rolled" or turned-under edges for pockets and other lined portions of projects such as book covers, wallets, and cases.

This demo shows another method of rolling inside pocket edges to give them a smooth leading edge, using a French skiving knife.
For this demo, I have a book cover for which I'm making sleeves
