Pergamano is so beautiful! I haven't been able to find the box with my Pergamano supplies since I moved and miss it.
I usually have mounted my Pergamano card to a slightly smaller "card" made of either one of Pergamano's pastel parchment papers or cardstock in a color that compliments the front of the parchment project. It can really change the tone and look of the card, so I usuallly try out several colors before deciding on a final choice. You can write or stamp inside the smaller card. I usuallly go only 1/8 to 1/4 inch smaller. Sometimes though, the project seems like it would just "go" better if mounted on a larger inside card - usually when there is a lot of delicate cutting and perforating around the edges of the card. A contrasting color will show through and highlight your work.
You really cannot adhere the smaller card with adhesive easily because it shows through on the front of the project. If there is no place within the embossing or coloring on the front where I can hide a few bits of mini glue dots or pergo-glue, I use gold metallic or a pearl colored thread or narrow cord, line up the inner and outer cards and mark a small hole about about one inch from the top and one inch from the bottom. I then thread the cord or thread through the holes and either tie it with a bow on the side of the card, or make a tassle at the bottom of the card. Since Pergamano is so elegant, I think the cord or thread fits with it well.
I do use my personalized stamp on the outside back of the card stamping it with versamark and then brushing over it with Pearlex. I made the mistake of once trying to heat emboss it - not a good idea with parchment.
