If you haven't done it already... I made invitations to a "Pirate Party" a few years back and I found the BEST way to burn edges is, to use the stove top. Simple as that. You have to put writing on BEFORE HAND but it works better than candles by far! The edges don't catch fire, they merely redden the edges and burn back without flame. It's less risky. Then to put it out when you're satisfied with the amount of burn you put it out. You just keep going till all your edges are done. I think you could probably roll them but I didn't think of that. If you want the look of flame, when your done burning the edges, carefully run the flat edges along the stove until the paper browns a little without catching it on fire.
