You'll need the corner of an anvil-like object, a hammer with either a slightly-rounded or resilient face [preferably both], and it'll be handy to have a vise.
For a simple rounded roll in a flat piece: scribe a line 1/4" from the edge of the piece, on the side you are rolling away from. Set the piece flat on the anvil so that the scribed line aligns with the edge of the anvil. Start tapping the edge of the piece so that it bends over the edge of the anvil. Make multiple passes, bending the edge a little at a time along the edge to be rolled. Once you've got a 90-degree bend, you can put the piece on edge in the vise, and keep tapping the bent edge till it's well past 90 degrees. Lacking a vise, set the piece on edge on top of your anvil.
Once your well past 90, you can set your piece flat on the anvil, with the bent part sticking up[insert your core wire now, if you're going to use one], and tap the roll the rest of the way down.
Adapt these procedures for curved rolls, and curved pieces, etc.
