I am having scrolls too. My h2b did all the wording and a friend has drawn an angel wrapped around the first letter. It also has a celtic design on it. We got the paper which looks like parchment from hobby world - 25 sheets for 3.25 so not a bad price. The celtic design is done with ink stamps and we are rolling and tying with red ribbon. We have one copy and are getting the others printed - about 45p a sheet so will add up for my large number of guests but hope it will be something different.
You can also do this effect on some computer software - would be cheaper that way tooo.
Good luck.
