Well, I've been going through the invitation ideas a lot lately. Since I'm going to be handmaking them, I want to have a pretty good idea what I want pretty early to have lots of time to work of them. But I'm having trouble deciding exactly what I want, there are a few options that I've seen with this style:
Casey: Ribbon in top half. Contrast paper backing/matting.
Holli: Ribbon in Bottom half. Contrast paper backing/matting.
Jana: Ribbon in top or bottom half (top shown). Single sheet cardstock, no matting/backing.
Here is a quick and horrible MSPaint representation of my colors put onto one of these invite styles.
