For example, the embossing folder here was one of the very first I bought. I saw this a version of this card on pinterest from jaymamalme.blogspot.com and loved it. It's cute and simple and won't be too hard to mail. (most of my cards are mailed) Not too much bulk.
card base: Soft Suede 8.5 by 11 cut at 4 1/4, scored and folded at 5.5
Layer: Pink Pirouette 4 by 5 1/4, embossed
I eyeballed the gift sizes starting at about 3 inches across and 1.5 inches tall from Cheerful Treat Designer Series Paper (DSP)
stamp: Tiny Tags in Lucky Limeade (retired) ink
the embossed layer was sponged with Soft Suede ink, as were all the edges
the ribbon is Chocolate Chip (retired)
