We have been reading through the book, Story of the World this year. If you have never seen or heard about this book I would totally suggest checking it out of the library.
There are 4 volumes that cover the history of the world. I bought volume one last year since it went with the history we were memorizing with Classical Conversations, but never got into it. I went ahead and ordered volume two for this year and we have been working our way through it and loving it. I ordered the activity book to go with it, which is not the cheapest thing out there. However, I think it's worth it. We have just finished reading about monks, monasteries, scriptoriums and how they would make books. To go with this, the activity book has an illuminated letter to color that we did.
I also looked up illuminated letters on the internet to give the kids other ideas of what they looked like. Here's a few examples to get you started.

We also had a monk's dinner that evening. The activity book had a recipe for this soup and recomended bread, cheese and apple slices to go with it. The kids enjoyed tasting a simple meal that a monk would eat. In all honesty, the simpler the meal, the more likely the kids will eat it anyways.
I can't believe how much I am learning each day!
