This first sample is very simple, and could be used as invitation or a program. Both pieces are AccuCuts dies, and I rounded the corners of the green piece. I don't know if it shows up in the picture, but I embossed a row of dots at the top and bottom using a Cuttlebug border embossing folder. I don't know the exact measurements, but it fits in a business size envelope.
The next sample features a purple base with white cardstock on top. I punched a strip of green paper with a Martha Stewart punch, and put some purple ribbon above that. Finished size is 5"x7".
The third sample is another AccuCuts die, cut out of the green paper. It has a white cardstock piece on the inside, and is wrapped with a purple strip that I punched with a Martha Stewart edge punch. I topped it off with some green polka-dot ribbon. Finished size is 5"x7".
